7 Tips to Prevent Asphalt Failure in San Jose's Fall Season

Protect Your Pavement Before Winter Hits

San Jose Asphalt: As we move into the fall season in San Jose, now is the perfect time to focus on preventive maintenance for your asphalt surfaces. The cooler temperatures and increased moisture during autumn (and the coming winter) can take a toll on asphalt, making it more vulnerable to damage. With the right care, however, you can prevent costly asphalt failure and extend the life of your pavement for years to come.

At Calvac Paving, we’ve seen firsthand the damage that lack of maintenance can cause. That’s why we’ve put together this guide to help you keep your asphalt in top condition as we head into the fall and winter months. 

San Jose Asphalt

1. Routine Inspections: Catch Issues Early

The first step to preventing your San Jose asphalt failure is regular inspections. As the weather starts to cool and moisture increases, small cracks and defects can worsen quickly. Make it a habit to walk your property and check for signs of wear and tear. Look for:

  • Small cracks forming in the surface
  • Potholes or depressions
  • Oil stains or areas of discoloration
  • Standing water that doesn’t drain properly

Catching these problems early is crucial. For example, small cracks may seem harmless, but they allow water to seep into the asphalt. When the temperature drops, the water freezes and expands, making the cracks larger and leading to more severe damage.

Pro tip: Conduct your San Jose asphalt inspections right after a rainstorm. This allows you to spot areas where water may be pooling, which is a key indicator of poor drainage.

2. Crack Sealing: The First Line of Defense

If you find cracks in your San Jose asphalt, don’t wait for them to get worse. Cracks allow water to penetrate the surface, which weakens the pavement structure over time. With fall rains and cooler weather coming, this process can accelerate. Crack sealing is a simple and cost-effective solution that prevents water from entering the asphalt and causing further damage.

The fall season is a particularly good time for crack sealing because the cooler temperatures allow the sealant to adhere better to the surface. Make sure to seal cracks that are less than 1/4 inch wide—anything larger may require more intensive repair work.

Real-world example: One of our San Jose clients noticed early signs of cracking on their parking lot last fall. By sealing those cracks before the heavy winter rains hit, they were able to avoid significant water damage and extend the life of their San Jose asphalt pavement by several years.

3. Sealcoating: Shield Your Asphalt from the Elements

Sealcoating is a protective layer applied to the surface of your asphalt that acts as a shield against the elements. This is especially important during the fall and winter months, when rain and cooler temperatures can weaken asphalt if it’s not properly protected. Sealcoating also helps protect against UV rays, oil spills, and chemicals that can degrade the surface over time.

In San Jose, where temperatures are relatively mild but moisture levels can increase significantly in the fall, sealcoating can make a big difference. It’s recommended to sealcoat your San Jose asphalt every 2-3 years, depending on its condition.

Seasonal focus: Sealcoating in the fall is ideal because it gives the asphalt a protective layer before the winter rains start. It also ensures that your pavement is in good shape when the warmer, sunnier months return, helping to prevent oxidation and sun damage.

4. Ensure Proper Drainage: Avoid Pooling Water

Standing water is one of the most common causes of asphalt failure, especially in the fall when rain is more frequent. If your pavement doesn’t drain properly, water can pool on the surface, leading to cracks, potholes, and even base layer damage. Proper drainage is crucial for maintaining the integrity of your asphalt.

During your fall maintenance, check for areas where water is collecting after a rain. These areas should be addressed immediately, either by adjusting the slope of the pavement or installing additional drainage systems to direct water away from the asphalt.

Pro tip: Check your drainage systems and make sure gutters and downspouts aren’t directing water onto your asphalt surface. Rerouting drainage can be an inexpensive way to prevent long-term damage.

5. Prepare for Winter: Protect Your Asphalt from Freezing

While San Jose doesn’t experience extreme freezing temperatures, occasional frosty mornings can still take a toll on your asphalt. Water that seeps into cracks and then freezes can expand, causing the cracks to widen. Over time, this can lead to potholes and more significant structural damage.

To prepare your asphalt for winter, make sure to complete any necessary crack sealing and sealcoating before the coldest months. This will ensure that your asphalt is protected from water infiltration and freezing.

6. Repair Potholes: Don’t Let Them Worsen

If you already have potholes in your asphalt, it’s important to repair them before they get worse. Potholes not only create safety hazards, but they also allow water to penetrate deep into the pavement, weakening the base layer and leading to more extensive damage.

Fall is the perfect time to fill potholes and repair damaged areas of your asphalt. Repairing potholes now can prevent them from expanding during the winter months when moisture is more prevalent, and repairs can be more difficult.

Real-world example: A property owner in San Jose had several small potholes last fall that went untreated. By the time spring came around, those small potholes had expanded significantly, requiring costly repairs that could have been avoided with timely maintenance.

7. Schedule Regular Maintenance: Long-Term Protection

The best way to prevent San Jose asphalt failure is through regular, ongoing maintenance. A well-maintained asphalt surface can last up to 30 years, while neglected pavement may need replacement after just 10-15 years.

At Calvac Paving, we recommend setting up a regular maintenance plan that includes routine inspections, crack sealing, and sealcoating every few years. By staying on top of repairs, you can avoid costly damage and keep your asphalt looking great year-round.

Conclusion

Preventing San Jose asphalt failure requires proactive maintenance, especially as we head into the fall and winter months in San Jose. From regular inspections and crack sealing to sealcoating and ensuring proper drainage, these preventive measures will help extend the life of your pavement and save you money in the long run.

protect your asphalt in Hayward, California with sealcoating

Back in 2018, we embarked on an ambitious asphalt replacement project at PEL Learning Center located at 24150 Hesperian Blvd., Hayward, CA. Not one crack has appeared to date, a testament to the quality of the installation and materials used. Despite the sealcoat being overdue, the pavement remains in excellent condition. As we revisit this success in 2024, we emphasize the crucial role of ongoing maintenance and timely sealcoating in extending the asphalt’s lifespan.

Protecting Your Asphalt: The Importance of Regular Sealcoating

Asphalt may be tough, but it’s not invincible. Regular exposure to UV rays, water, and oil can degrade its structure. That’s why consistent sealcoating is essential—it serves as a shield against these elements, preventing damage and maintaining the integrity of the pavement. Although our sealcoating was overdue, applying it has significantly boosted the longevity of the surface, enhancing its appearance and positively impacting customer impressions of the property.

Updated Project Details

The integrity of the asphalt laid in 2018 remains intact, showcasing the enduring quality of our initial work. Recently, we’ve reinforced this durability with a specialized sealcoating regimen:

  • Preparation: The asphalt surface was meticulously cleared of all debris.
  • First Coat Application: We applied a robust sealant mixed with two pounds of sand per gallon, enhancing traction and durability.
  • Second Coat Application: A second sealcoat layer was added to ensure comprehensive protection and enhanced resilience.

Benefits of This Approach

  • Extended Lifespan: The dual-layer sealcoating has effectively increased the pavement’s expected life. Applying two coats of sealer instead of one coat leads to a superior finish. These water-based sealers cure and form a protective film primarily through the evaporation of water.
  • Cost Efficiency: For high-traffic commercial parking lots, the enhanced durability provided by regular maintenance significantly reduces the frequency and severity of necessary repairs. This extended lifespan of the pavement not only cuts long-term expenses but also minimizes disruptions in busy areas, ensuring a smoother operation and a more consistent customer experience. By investing in preventative care, businesses can substantially decrease the overall cost of ownership and maintain the aesthetic appeal of their property, boosting its value and appeal.
  • Aesthetic Enhancement: The sealcoating, complemented by precise striping, has revitalized the asphalt’s appearance, enriching the overall look of the property. This combination not only enhances the visual appeal but also improves navigational clarity, making parking areas more organized and visually striking.

Conclusion:

Our 2018 project at PEL Learning Center in Hayward stands as a prime example of how diligent maintenance and regular sealcoating are not just beneficial but essential for prolonging the life of asphalt paving. With the right care and strategic interventions, such as those implemented at 24150 Hesperian Blvd., asphalt becomes a smart investment in the longevity of a property’s infrastructure.

asphalt parking lot paving work in northern california

Are you a commercial property owner wanting to have your parking lot paved? Or are you a homeowner planning to upgrade your driveway? Whatever your reason is, you can never go wrong with asphalt paving. 

Commercial property owners often favor asphalt paving over concrete for its quick construction, affordability, strength, and easy maintenance. On the other hand, homeowners prefer asphalt driveways because they offer affordability, durability, and aesthetic appeal, lasting up to decades when properly installed. 

That is why hiring a trusted asphalt paving company in San Jose with the necessary skills and equipment is very important to make sure that your pavement can stand the test of time. Always remember that choosing the right asphalt paving contractor is the key to a successful project outcome. Opting for the lowest bid isn’t always the best choice, as various factors can affect the quality of the final result.

So, how do you identify and choose the best asphalt paving company in San Jose? In this blog, we’ll narrow everything down into 10 easy-to-follow tips for you to make the best decision for your asphalt project:

1. Do Some Research

When choosing the best asphalt paving company, it’s always better to start by conducting your own research. By researching, you will be able to make sure that you are selecting the best and quality company for your asphalt paving project. You can use search engines such as Google or Bing. Remember that the top results may not always be the best choice for you so take some time to read and research about other companies as well. Make a list of all the possible asphalt paving companies according to your own criteria and slowly narrow them down from there. By conducting your own research, you can avoid biased reviews and properly find the best asphalt paving company for you. 

2. Read Online Reviews

When looking for an asphalt paving company, it’s important to check their reputation through online reviews. Never forget to do this step! Take the time to read both positive and negative reviews, considering the reasons behind them. Try to look for consistent feedback across different review platforms such as Google reviews, Yelp, Facebook, Instagram, or even their website to get a clear picture of the company’s reputation.  

3. Look at Examples of Their Work

To assess the quality of an asphalt paving company’s work, take a look at examples of their previous asphalt projects. You can do this by checking their online gallery or asking for a list of locations that they’ve worked on to drive by and see the pavement firsthand.

4. Ask for Recommendations

If you need some recommendations, start by asking friends, family, neighbors, and coworkers. They can share their firsthand experiences and vouch for companies they’ve worked with. People are often eager to recommend companies that have done a great job for them. 

5. Check Credentials & Licensure

When hiring an asphalt paving contractor, it’s important to ensure they are properly licensed for the work they’ll be doing. You can ask them directly if they can provide proof of licensure then verify it by checking it on your state’s website to make sure it’s current. This helps ensure you’re working with a qualified professional who meets the necessary standards for the job.  

6. Insurance

When choosing the best asphalt paving company in San Jose, you should ask the contractor if they have insurance, including general liability and workers’ compensation. You can request proof of insurance to verify coverage for bodily injury and property damage. Make sure to receive an insurance certificate directly from the contractor’s insurance agent for both policies. Proper insurance coverage will give you peace of mind as it removes financial responsibility from your family in case of accidents or any property damage.

7. Check Their Status With the Better Business Bureau

To ensure you’re hiring a reputable asphalt paving contractor, it’s wise to check their status with the Better Business Bureau (BBB). The BBB keeps records of businesses and assigns ratings based on various criteria, including customer disputes and resolutions, and the company’s longevity. You can easily search for asphalt paving companies on the BBB website by typing in keywords like “asphalt contractor in San Jose” This will provide you with a list of companies along with their ratings. You can also see if they have any unresolved complaints from previous customers. If you want, you can also contact the BBB directly for more information. 

8. Experience

Always consider the asphalt paving company’s level of experience, which is crucial for a successful project. Experienced contractors have the knowledge and skills gained from years of paving driveways, parking lots, and roads. They understand which type of asphalt is best suited for different purposes, ensuring a quality and long-lasting outcome and will potentially save you money in the long run. Check how long the company has been in business, as longevity often indicates reliability and quality workmanship. A company with a good reputation is more likely to deliver satisfactory results. Additionally, inquire about the contractor’s specialization and the types of jobs they typically handle.

9. Get Multiple Quotes

When planning your asphalt paving project, it’s important to get estimates from multiple contractors to ensure you’re getting the best services for your needs. Getting quotes from different commercial asphalt companies in San Jose allows you to compare prices and services, helping you make an informed decision. Be cautious of unusually low bids, as they may indicate subpar work or the use of low-quality materials.

When requesting quotes, provide detailed project specifications to ensure accuracy. Pay attention to the compacted thickness of the asphalt included in each quote, as this can affect the durability of your driveway. Take your time when comparing paving quotes and avoid contractors who pressure you to make a quick decision. 

10. Customer Service

Last but definitely not the least, consider their customer service. Pay attention to how they answer the phone or respond to online inquiries. Look for professionalism and promptness in their communication.

A reputable company will provide you with an official written estimate that includes all costs and a clear timeline for the project. If you have any concerns during the screening process, trust your instincts and don’t hesitate to look elsewhere. When you choose an asphalt paving company that values good customer service, you will have a smoother and more satisfactory experience from start to finish.

By following these steps and conducting thorough due diligence, you can hire the best asphalt paving contractor in San Jose who will deliver a quality job and provide you with peace of mind throughout the project. Remember that investing time in selecting the right contractor upfront can save you from potential headaches and costly issues down the road.

Bay Area Golf Course Asphalt Repair

Revitalizing Poppy Ridge Golf Course!

At Calvac Paving, we know a thing or two about asphalt repair and Golf Courses.

So when Poppy Ridge Golf Course called us to bid on a project to rehab an extensive areas of failed asphalt encompassing the road leading to the golf course and the parking area itself, and to reseal and restripe the parking area and drive entrance, we were pleased to submit our expertise and cost for consideration. Soon thereafter, we learned we had been awarded the project at 4280 Greenville Road in Livermore.
 
To achieve the repair, we provided 4” asphalt repairs and two coats of seal followed by restriping. This required excavating the failed asphalt and recompacting the subgrade beneath the asphalt paving. Then the hot mix asphalt needed to be placed in two 2” layers, or “lifts,” using 3/4” asphalt on the base lift and ½” medium asphalt on the surface lift. Covering 4,000 +  square feet of surface area. This ensures strength, flexibility, and density within and between the asphalt layers, while minimizing air voids which can facilitate water infiltration and lead to premature asphalt failure over time.  
 
Once the subgrade and the lifts had been individually compacted, we provided two coats of Reed and Graham’s OverKote, an asphalt emulsion seal for asphalt which incorporates a latex additive. This step gives a smooth, finished appearance to the asphalt, adds surface resiliency and increases water and dust resistance, extending the operational lifespan of the asphalt. The staff and patrons of the golf course were extremely cooperative and understanding of our schedule and the project went very smoothly.
 
We’re proud to announce that Poppy Ridge Golf Course has already recommended us for similar projects on the strength of our work here, and we’re excited to be able to demonstrate the quality and efficiency of our work once again as the leading Bay Area Asphalt repair company.
 
Calvac Paving has been serving the Bay Area since 1972, and we’re proud to bring the same great results to every project we work on.

8 Signs Your Asphalt May Be Failing

Facebook
LinkedIn
Twitter
Pinterest

Asphalt is a very versatile and durable paving material. Its resilience and flexibility make it an ideal surface for everything from eight-lane superhighways to driveways to parking lots. However, asphalt does require care and maintenance to function at peak performance, and it can fail for several reasons. If you see any of these warning signs of failing asphalt, quick action can save you a lot of time, money, and hassle. Here are eight signs your asphalt may be failing—and what you can do to fix them!  

1.  Alligatoring

Alligatoring is called that because of its appearance: interconnected cracks that look like alligator skin. It is an indication of load-related deterioration which could be caused by a weakened or improperly compacted subbase material, excessive traffic loading, inadequate pavement thickness, or a combination of these factors.  

2.  Edge Cracks

Edge cracks are found within 1-2 feet of the outer edge of the asphalt surface, running longitudinally, or roughly parallel to the outer edge. These cracks are caused by improper support of the paving surface at the margins.  

3.  Reflective Cracks

Reflective cracks most typically form in joints or areas of concrete or asphalt paving which have been previously repaired, such as with crack sealing or where a temporary corrective overlay has been placed to relieve stress on deteriorated paving. These cracks form because of continuing movement of the old pavement due to continuing traffic load.  

4.  Slippage Cracks

Slippage cracks are easily identifiable because of their crescent shape. They occur either due to poorly bonded pavement layers or an asphalt mix design which is insufficient to the demands of the traffic patterns. These cracks appear because of forces applied by turning or braking vehicles, which cause the pavement to move slightly at first but with accelerating damage to the surface the longer the underlying cause goes uncorrected.  

5.  Rutting And Depressions

Ruttingis caused by weakness of the subgrade or base soil layers, instability of an asphalt mix, insufficient pavement thickness, or poor compaction. Rutting is a linear, surface depression of the wheel path caused by deformation or consolidation of any of the pavement layers or subgrade. Depressions,also known as birdbaths, are localized areas of pavement surface failure caused by poor initial construction techniques that undermine the asphalt over time. These may occur on their own or in conjunction with other failure indicators. If left unchecked, depressions can become potholes(see #8).  

6.  Asphalt Patch Failure

These failures are easy to spot because they’re very localized to the area where a patch was placed, and characterized by unevenness, deflection, or stress cracking along the perimeter of the patch. They are caused by either not fully removing the damaged area to be patched, or not allowing a minimum of one extra foot around the perimeter of the patch area to ensure the patch is bonding to an uncompromised surface. The rate of patch deterioration is influenced by materials selection, compaction, and the quality of the surrounding pavement as well as the underlying subbase. While the latter is not typically visible, adding one additional foot around the patch can help patches last longer and function better under load.  

7.  Raveling

Raveling is caused when the aggregate particles in the asphalt cement wear away under traffic forces. This condition suggests either that a poor-quality mixture was used or the asphalt surface has hardened enough to no longer be supple and flexible.  

8.   Potholes

These bowl-shaped holes are caused by localized disintegration of the pavement surface. Potholes are usually the result of another type of distress that has not been properly addressed. Segregation, failed patches, and cracks can all lead to a pothole over time. Weak spots and localized areas of improper or insufficient compaction in the subgrade or subbase, or poor asphalt mix designs, can accelerate the degradation of the pavement surface and the formation of potholes.   When you notice indications of paving failure, bring in an experienced paving contractor as soon as possible to restore the surface and minimize downtime, expense, and the risk of further, more severe failure in the future. Calvac Paving has been proudly serving the Bay Area and beyond for over 45 years, and we’d like to put that experience to work for your next paving repair or new construction project.

Calvac Paving in San Jose commercial services

Have you ever thought about the signals your paving might be sending? Most people don’t, but properly executed concrete and asphalt commercial paving can make a big difference in how your property is perceived, from the initial impression people receive just driving by to potential customers or even buyers. 

If your property is used for regular commerce, such as a shopping center, big-box store, church, or apartment complex, you may find you don’t entice the sort of clients and visitors you’re hoping for if your asphalt surfaces aren’t up to par. 

Even worse, it could adversely affect the bid numbers your property receives if you decide to sell!

If you’re noticing cracking, discoloration, warping, areas of exposed aggregate, faded striping paint, or other common signs and symptoms of asphalt and concrete failure, you might be tempted to just ignore it—or worse, try to figure out a fix for satisfactory asphalt repairs with the staff and materials available to you and your company. 

But DIY asphalt repair isn’t always the best way to deal with problems like this. If they’re not dealt with by reputable asphalt paving company contractors, you could be left with an even bigger problem than you started with—and your customers, visitors, and potential buyers might be scared off by poorly placed asphalt paving or improper asphalt maintenance.

Calvac Paving is the asphalt company the Bay Area and Northern California trust for all your concrete and asphalt construction needs, delivered on schedule and on budget. 

So if the points above haven’t convinced you that you really do need the help of professional asphalt paving companies to make sure your asphalt driveway, parking areas, and roadways are up to scratch, here are seven reasons why quality asphalt paving is a must for commercial property owners!  

1. Enhances Curb Appeal

Commercial asphalt paving contractors can help improve the aesthetics of your property. Quality asphalt paving will enhance the curb appeal of your commercial property, making it look more professional and attractive to potential customers. Whether it’s a convenience store or a chain of community centers, even small cracks in your pavement can add up to high costs in lost revenues and interest for your business.

2. Boosts Property Value

Quality commercial asphalt paving is an investment that can increase the value of your commercial property. It can also make your property more appealing to potential buyers or tenants now and in the future.

3. Provides Safe and Smooth Surfaces

A quality commercial asphalt paving contractor will provide asphalt installation that delivers a smooth and level surface that is safe for pedestrians and vehicles and retains striping and marking paint at maximum visibility for a longer period too! A poorly paved surface can be dangerous, causing accidents and damage to vehicles. It’s also an ADA compliance infraction that could rack up big fines or even shut your business or property down if it’s not corrected.

4. Reduces Maintenance Costs

Quality asphalt paving can help reduce maintenance costs. A well-paved surface is less likely to develop cracks or potholes, reducing the need for frequent repairs.

5. Improves Drainage

Commercial asphalt paving contractors can design, build, and install a drainage system that prevents water from pooling on your property. This reduces the risk of damage to your pavement and prevents accidents caused by slippery surfaces. It also helps extend the life of your asphalt paving, keeping it looking and performing great for longer, reducing the future cost of maintaining and repairing your asphalt over time.

6. Enhances Sustainability

A quality commercial asphalt paving contractor will use sustainable materials and techniques to create long-lasting pavement. This reduces the environmental impact of construction on your property and the world around us and helps you meet sustainability goals. Going green, or at least greener means everyone wins!

7. Increases Customer Satisfaction

A well-paved parking lot or driveway can help improve customer satisfaction. It provides a positive first impression of your property, making customers feel more comfortable and safer while visiting your business while sending a clear, simple message: “We’re up to the job!” This is a crucial first step in the customer experience because if your facilities don’t look like they’re up to par, why would their expectations include the excellent, even exceptional, customer service and results you and your experienced staff strive so hard to provide?

Frequently Asked Questions About Why Quality Asphalt Paving is a Must for Commercial Property Owners

Calvac Paving is the asphalt paving contractor commercial businesses and government entities in Northern California trust for parking lot and driveway paving that lasts longer, as well as roadways that will stand the test of time!

Question: What Is A Commercial Asphalt Paving Contractor? –Reynaldo, San Jose, CA

Answer: A commercial asphalt paving contractor is a professional who specializes in the construction and maintenance of commercial properties such as parking lots, driveways, and roads using asphalt, as well as commercial paving and coating operations for other applications. But caveat emptor! Not all asphalt commercial paving companies are created equal. A commercial contractor who can handle a simple, minor repair job that only requires a touch-up on asphalt sealcoating to bring the surface back to life again may find themselves out of their depth on a job that requires a complete tear-out and reinstallation because the cracks have infiltrated through the entire asphalt mat, allowing in water, frost, and biological and environmental contaminants that can undermine asphalt’s flexibility and resilience. It’s important to always check the expertise of the company you’ve chosen for your commercial paving and coating needs, so you know you’ll get great, durable results that last far beyond the day the contracting company leaves the site!

Question: What Is The Typical Lifespan Of An Asphalt Surface? –Artie, Los Gatos, CA

Answer: The typical lifespan of an asphalt surface can vary depending on the quality of materials used, how well the ground preparation was executed before the final mat was introduced, the amount of traffic it receives, and the level of maintenance it receives. Generally, an asphalt surface can be expected to last between 15-20 years with proper care and maintenance.

Question: What Services Do Commercial Paving Contractors Offer? –Jeanette, Santa Clara, CA

Answer: In general, a reputable, established commercial paving company will typically offer a range of services, including new construction, repair, maintenance, and replacement of asphalt surfaces. Commercial contractors can also provide asphalt and concrete paving repair services, such as seal coating, striping, and crack filling, to extend the service life of your paving, so it looks and works better for longer.

Question: How Do I Choose A Reliable Commercial Asphalt Paving Contracting Company? –Chuck, San Francisco, CA

Answer: To choose a reliable commercial asphalt paving industry contractor, you should look for a company that has a good reputation, proper licensing, insurance, and experience in the field. You can also ask for references and check reviews from previous clients. If available, review the project gallery of previously completed projects to make sure the results they’ve delivered in the past are in line with your expectations for the future of your project. It’s even better if you can independently contact communities or municipal office personnel, such as a project manager, who has interacted with the company in the past and can give you an unvarnished review of your paving contractor’s services.

Question: What Factors Affect The Cost Of Commercial Asphalt Paving? –Thomas, Hobart, CA

Answer: The cost of commercial asphalt paving can be affected by various factors such as the size, scope, scale, and complexity of the paving project, the quality of materials used, the location, and the equipment and labor required for the job. For example, a job that only requires a pump truck with a single two-person paving team to dispense seal coat or crack sealer is going to cost a lot less money than one that requires a lowboy, pavers, a parade of asphalt delivery trucks, a front-end loader, and steel-drum and rubber-tire rollers, plus an experienced and seasoned roster of multiple paving crews to run and manage all this equipment. In general, residential driveways need a lot less equipment than most parking lots, and most parking lots (excluding schools and universities) typically require less equipment than roadway construction does, which obviously has a large impact on the pricing range you can expect for your job.

Question: How Long Does It Take To Complete A Commercial Asphalt Paving Project? –Ilsa, Sunnyvale, CA

Answer: The time it takes to finish a commercial asphalt paving project depends on the size, complexity, type, and requirements of the project. However, with proper planning and preparation, most projects can be completed anywhere from a day or so after starting to a few weeks, in the case of large industrial projects. This does not include the time to survey, plan, make sure the necessary crews, equipment, and materials are reserved, set up any necessary traffic controls, and similar “pre-work” logistics tasks that need to be done but often get overlooked when considering a deployment and execution schedule.

Question: I Manage The Development Of Townhouses, And I’m Considering Having My Maintenance Staff Work On Some Paving Problems I’ve Noticed. What Are The Benefits Of Hiring A Commercial Asphalt Paving Contractor? –Karen, Palo Alto, CA

Answer: While going the DIY route to stay within budget can be very tempting, it’s almost never the best way. What videos from YouTube or Instagram often don’t tell you are things like why this specific solution worked, or that one didn’t. They also don’t address hidden problems you might encounter trying to do the work yourself, such as water or frost infiltration into the mat, which can compromise its performance and presage more serious problems in the making, which may mean replacement rather than repair, is the right call. Hiring a commercial asphalt paving contractor at the outset can help ensure that your project is completed efficiently and to a high standard. They can also provide professional advice and guidance on the best solutions for your specific needs and situation. Obviously, there’s a lot more that goes into helping keep your paving looking and working great than just keeping it clean.

5 Major Asphalt Advances to Watch in 2022 From Calvac Paving

From the highway to the driveway, asphalt paving gets you where you need to go. Humanity has been using asphalt and bitumen for projects as diverse as waterproofing, shipbuilding, and road paving for millennia, and it has continued to prove its utility at every turn. In 2022, Calvac Paving is excited about some new advances in paving technology that could be game-changers for drivers, owners, stakeholders, and local, state, and federal authorities and agencies alike. These are the five major asphalt advances you’ll want to watch in 2022, brought to you by your friends at Calvac Paving!  

Alternative Paving Materials

From cigarette butts to recycled plastic to rubber-modified asphalt (RMA), scientists worldwide are exploring the application of old materials, used in new ways to enhance the strength, longevity, sustainability, recyclability, and resilience of asphalt paving. These alternative paving materials may help combat issues like the “urban heat island” effect, keeping asphalt-paved surfaces cooler and allowing them to trap less heat year-round. They also offer new ways to reduce waste, reuse materials, and recycle “junk” materials that are typically discarded, helping break the waste chain and creating a healthier environment by keeping these materials out of landfills, waterways, and oceans.  

Smart Pavement

Technology may soon make your morning commute or your summer trips safer and easier, with fewer bumps and less noise! Integrated sensors that report everything from traffic conditions to overall roadway and pavement health are being tested around the globe. Nanoparticle-based noise- and vibration-damping adhesive binders for asphalt mixes are under investigation as a potential solution to problems such as roadway chipping and pitting. And roadways that charge electric vehicles as they drive using wireless recharging technologies are in active use or the planning stages from Sweden to Michigan to Norway, solving one of the EV’s biggest hurdles while also making paving even more environmentally friendly!  

Asphalt Continues Its Reign As The World’s Most Recycled Material.

  Roughly 100 million tons of asphalt pavement mix are produced each year globally. Of that amount, an estimated 95% is reclaimed, reused, recycled, or repurposed, making asphalt one of the planet’s most readily recyclable materials. Perhaps most importantly, recycling asphalt helps keep costs lower and reduces reliance on foreign oil to create the bitumen binder that gives asphalt paving its flexibility. With all these factors going for asphalt, it’s reasonable to expect even bigger pushes to maximize asphalt recycling up to a full 100% in 2022 and beyond.  

Inflation And Rising Oil Prices

Between the war in Ukraine and US embargos on Russian goods, including oil, the continuing effects of the COVID-19 pandemic on shipping and trade, and a period of high inflation, prices are only getting higher for just about everything—and asphalt pavement is no exception. Recycling and the use of alternative paving materials will help offset this increase greatly, but paving contractors and stakeholders can still expect to see reduced profits and higher up-front costs, at least through the summer.  

Striping

 Some of the biggest advances and hottest trends in paving technology don’t really have to do with the pavement itself—but the paint! Striping is a perennial headache for entities from the federal government all the way down to small business owners trying to keep their parking stalls and handicapped spaces ADA-compliant, but new formulas and application methodologies appear poised to change that in 2022. New advances in striping paint include more eco-friendly options, nanotechnology and microfibers for increased durability and longer utility life, and additives and refined formulas for heightened visibility. Autonomous, self-piloting robotic paint sprayers which deploy striping more uniformly, more accurately, and with a greater level of precision than humans are capable of are making a big impression across the industry.   At Calvac Paving, we’re excited about (most of) what 2022 has in store for the paving industry, as well as how new advances and technologies are going to change both the paving industry and the face of our world. Since 1974, we’ve been committed to making the use of concrete and asphalt paving in construction as efficient, cost-effective, and environmentally friendly as possible. Because of this commitment to a greener, cleaner planet for all, and better-forming pavement applications for our customers and stakeholders, we’re looking forward to seeing the next big advances and putting them to work!

Five Reasons, The Best Time to Maintain Your Asphalt Is NOW!

The last 18 months have been rife with uncertainty and riddled with worry for nearly everyone. With businesses closing temporarily or permanently, the Bay Area’s paving situation has never been as dire as it is now. The fact is, if your parking lot, driveway, and other paving problems aren’t corrected early, they’ll get worse and more expensive to fix later. Here are five reasons the best time to maintain your asphalt is NOW!

1. Fluctuating Oil Prices

The price of oil impacts everything, perhaps especially in the construction industry. Asphalt and concrete batching and production processes are uniquely affected by the cost of oil. In July 2020, the cost of asphalt tumbled to a low not seen since March 2017. One year later, the price has increased by nearly 50%, spurred on by rising oil prices and a concurrent rise in the cost of refining, processing, and batching. With prices going up, now is the best time to lock in current rates for asphalt and concrete before the cost jumps even higher.

 2. Curb Appeal

How can you tell the difference between a closed business and a business that’s open and ready to take care of its customers? The truth is your customers can’t, especially if they’re driving by on the street. Cracked, faded, potholed parking lots with worn-out striping are unattractive to the eye and send an unflattering message to potential clientele. By repairing your parking lot, access-ways, and other curb and drive installations, you clearly communicate that you’re open for business, ready to get to work, and able to assist your customers with all their needs.

 3. Safety

Did you know that cracked or potholed asphalt, offset sidewalk slabs, and other defects and damaged portions can be a safety hazard? It’s true! If a customer trips and falls because of poorly cared-for paving, your business may be liable for any injuries they sustain. Such hazards can also impede disability access to your business and maybe an ADA violation with a fine of up to $75,000 for the first infraction and $150,000 for each subsequent violation. When you add up the stiff financial and reputation costs of noncompliance and the potential for injury to your staff, customers, and the general public, having your parking lot and sidewalks repaired looks like a pretty good bargain.

4. Weatherproofing

When cracks form in asphalt paving, it allows water to infiltrate the subbase. A small trickle of water isn’t a big deal, though, right? Unfortunately, no. As water seeps into the pavement, it wears and washes away the surrounding material and pools within the matrix, allowing plant seeds to take root and start to grow. During colder weather, it may freeze and expand. These erosive processes accelerate cracking and pothole formation as well as undermining the structural integrity and flexibility of the overlying surface. At a certain point, the paving will be beyond repair and will have to be completely removed and redone to work properly. A well-maintained parking lot will perform and look better for years to come.

 5. Increase And Safeguard Your Property Value

Faded, cracked, or faulty paving can be expensive in more ways than you think. It can also drag down the property value, especially if you’re considering selling in the near future. If your paving looks good, it will also perform well for years to come, making the property a better investment for anyone who might end up buying.

All in all, maintaining your asphalt paving is a smart investment with a lot of benefits and virtually no downside over time. Whether you need a simple sealcoat and restriping, a spot patch and repair on a faulty section, or a complete tear-out and rebuild of your asphalt and concrete paving, Calvac Paving is here to help with proven, durable results that give you, your tenants, and their customers the great performance and appearance they expect and deserve.

10 Ways to Prepare Your Asphalt for Summer

calvac paving asphalt paving work

Whether it’s a roadway, a driveway or a parking lot, asphalt takes a pounding over the fall and winter months. The cooler temperatures and more frequent rains can take a toll on even the most robust and well-constructed asphalt pavements. To ensure maximum safety and durability for your asphalt and the people who travel and park on it, Calvac Paving presents ten ways to prepare your asphalt for summer!  

1.  Take A Closer Look.

Asphalt is very durable and resilient, but there are a number of ways it can fail, so it’s a good idea to have a thorough walkthrough at least quarterly. You should check the condition of your asphalt more frequently in cases of unusually heavy or inclement weather, or if you notice indications of a problem like water flowing down the middle of your lot or roadway.  

2.  Cracked-Up Asphalt Isn’t Funny. 

Surface cracking often indicates that the subgrade beneath the asphalt is failing, this will also allow water penetration into the subgrade. In these cases, depending upon the severity, the affected problems such as potholes, alligatoring, or area(s) need to be removed and replaced.  

3.  Paint It Black.

If your asphalt looks gray rather than black, has a pitted look or you notice deep cracks which may allow water to infiltrate to the subbase, it’s time to engage in crack filling and sealcoating, to help preserve and protect the asphalt and retard further damage.  Note: Most unsealed asphalt has a rough and somewhat textured surface, because of the placement methodologies and the type of hot mix used. The larger the aggregate in the mix the stronger the pavement, but you give up the smooth appearance The solution to this rough surface is twofold. First, an admixture of 2% latex per gallon of raw seal coat is added to both coats of material. secondly, adding one to four pounds of sand to the seal coat on the first coat will add necessary fine aggregate to fill the voids in the asphalt pavement. No sand is added to the second coat. This works to ensure a better looking, longer-wearing surface.

4.  Don’t Stand For It!

Standing water can be a symptom of subsurface issues with a section of your asphalt, usually caused by compaction failure in the subbase. Not only can standing water erode the surface as we’ve already discussed, but it can also undermine the integrity of other sections as the water is forced out of the depression and follows the drainage profile of the area in question.  

5.  Rainbows Belong In The Sky, Not On Your Asphalt!

If you notice iridescent or rainbow-colored patches, these should be cleaned off as soon as possible. Oil and fuel spills can degrade the asphalt’s surface quickly, creating imperfections which over time can become full-fledged failures, reducing your asphalt’s performance and lifespan.   

6.  Clean It Up.

In addition to the fuel and oil spills mentioned above, it’s always a good idea to keep your asphalt clean and clear of debris such as garbage. Food products, in particular, should be cleaned up quickly, because these tend to have a relatively high acid content, e.g., ketchup, hot sauce, salad dressing, which then lingers on the surface, promoting deterioration of the asphalt. Besides, it just looks nicer!  

7.  Root It Out.

If you have trip hazards such as uneven areas or raised roots, now is an excellent time to get them corrected. Trip hazards can be an expensive liability and can presage surface failure later depending upon the nature, type, and expression of the hazard. If possible, identifying and removing these hazards early can extend the life of your asphalt and help keep your insurance premiums down as well.

8. Traffic Control Is Important.

Older and graying pavements make it significantly more difficult to see the traffic markings. This can lead to potentially hazardous situations. Often the markings, arrows, crosswalks, stops and bars can become unrecognizable because of “ghosting”. This is the prior striping bleeding into view and confusing the drivers and pedestrians and leading to potential accidents. This condition is usually timely with the need to seal coat the pavement. Seal coat and restripe will solve this for years to come. This will also allow the property to be brought up to the current Building Code.

9.  Time Is Not On Your Side.

By the time most people notice a problem with their paving, the damage could be far more extensive than even a detailed site walk can really pinpoint. Frequent examination and correcting areas which show indications of failure as soon as possible after they’re noted can help prevent costly, time-consuming, and unnecessary repairs.  

10.  Call In The Professionals.

A paving job done poorly can often be worse than no repair at all. That’s why it’s worth your while to bring in pavement professionals with a solid track record of proven results. Calvac Paving has been serving the Bay Area since 1974, and we have the experience, resources, and personnel to do the job right the first time, every time.

How Long Does Asphalt Take To Dry?

One question we often hear at Calvac Paving is about asphalt cure times. This is a great question because understanding how the asphalt curing process works helps you understand when you can safely stripe, park, walk, and drive on the new asphalt parking lot and what sort of performance you can expect from your asphalt long-term. Let’s take a closer look at how the asphalt installation process works and how this affects the asphalt curing process!

 

 Asphalt Surface Installation

 

Most asphalt paving companies prefer not to place a fresh asphalt surface if the ambient temperature is outside the range of  50°F-90°F. If it’s too hot, asphalt will not cure quickly enough.  Paving when it’s too cold can cause the asphalt crack as it rapidly cools. Weather conditions can make a difference as well. If you watch carefully, you’ll notice paving companies rarely place asphalt in heavy rain. While it is possible to pave asphalt outside these parameters, it requires special preparation and oversight.

The rules for hot asphalt patch, resurfaced asphalt sealcoating and cold patch asphalt placement are a little different, so for purposes of this discussion, we’re going to focus on a clean installation on grade for commercial or residential paving like parking lots or a driveway.  

 

 How Long Does Asphalt Take to Cure?

The curing time for asphalt depends on the asphalt mix design, the oil content, the temperature of the mix, the thickness of the paved asphalt layers after compaction, and the temperature and weather conditions when the mix was placed. Generally, you can open new asphalt to public foot and vehicle traffic 48-72 hours after it is placed because this allows time for the asphalt to harden, but you may need to allow a bit more time during hot weather. Asphalt doesn’t fully cure for 6-12 months, so it’s important to keep a close eye on it during this time because it will be less resistant to damage.

The reason we stress the difference between “curing time” and “asphalt drying time,” even though they’re often used interchangeably is that asphalt is designed to be flexible. For it to remain flexible, it has to retain a certain amount of moisture. Water infiltration in paved asphalt driveways, parking lots, roadways, speed bumps, and other asphalt surfaces is the primary factor leading to a blacktop drying out. The water washes away the oil which keeps the asphalt overlay flexible and resilient. You can tell when asphalt dries because you’ll notice cracking, warping, raveling, and loose aggregate appearing on the surface of the matrix, especially sand and other fine aggregates. Fortunately, it takes months to years of asphalt drying time to start noticing signs other than cracking.

 

What Can I Do to Not Allow My Asphalt to Dry Out?

 

Good roadway and parking lot maintenance programs can help prevent a lot of problems. Putting down asphalt seal coating on a regular basis, especially when you freshen up your street or parking lot striping, can help prevent more costly asphalt repairs down the line. This is also a great time to do any basin repairs and crack filling, as catching these problems early, when they’re small, can keep your asphalt fresher and more flexible for a lot longer.

Asphalt sealer drying times vary, but 4-8 hours to dry is usually enough for your sealer to ensure it will keep water out. However, the full drying process for the sealer takes around 24 hours, and it’s important to allow your sealcoating to dry completely before line striping for maximum resiliency and effectiveness. As with any other kind of asphalt sealant, you want to allow crack sealer to cure for at least 24 hours in perfect conditions, and add a day for cool, cloudy, or high-humidity conditions just to be on the safe side.

 

 Final Thoughts About How Long It Takes Asphalt to Dry

 

Of course, the best mix design in the world won’t do you any good if it’s improperly placed, if your striping doesn’t meet the latest ADA criteria or if you don’t take proper care of it.
