The Lifespan of Asphalt Paving & How to Expand It
If put down properly, asphalt paving can be a very durable and reliable surface for lots, roads and driveways that allows for a very smooth, professional look for decades. However, as with any type of investment, there are certain factors influencing the lifespan of asphalt that should be known in order to ensure its greatest longevity.
Now, without further ado, let’s learn more about the average lifespan of asphalt paving and practical strategies to extend its longevity.
How Long Does Asphalt Paving Last?
On average, a well-installed and properly maintained asphalt driveway can last between 15 and 30 years. Several factors influence this range, including climate, traffic, and the quality of the installation. While heavy-duty roads can withstand years of constant use, residential driveways or low-traffic areas typically have a longer lifespan due to lighter wear and tear.
If you’re considering asphalt paving and wondering about its longevity, it's essential to evaluate your specific needs and consult reputable paving contractors who understand local conditions. For instance, if you’re searching for “paving contractors near me” or “driveway paving Ottawa,” you’ll want experts who are familiar with Ottawa’s seasonal climate challenges, as this can heavily impact your asphalt paving’s resilience.
Key Factors That Affect Asphalt Longevity
Understanding the factors that affect asphalt’s lifespan can help you make informed choices and set realistic expectations. Here’s what to consider:
Climate & Weather Conditions
Asphalt paving is especially sensitive to temperature changes. Asphalt in places with cold winters and hot summers – like Ottawa – gets plenty of expansion and contraction, which causes cracks and potholes. It is important to maintain the quality of existing surfaces through regular repair maintenance, particularly in freeze-thaw regions.
Quality of Installation
The quality of installation is a major determinant of asphalt’s longevity. A reputable asphalt company uses the right mix of materials and skilled professionals to ensure the surface is even and free from air pockets. In addition, proper layering, grading, and compaction create a solid base that helps the pavement withstand years of traffic.
Traffic Load
The type and amount of traffic asphalt endure also matter. Residential driveways, which support only light vehicles, will generally last longer than commercial parking lots with heavy trucks. When discussing your project with a driveway paving Ottawa, mention the anticipated load to ensure that the correct thickness and compaction methods are used.
Drainage & Water Exposure
Standing water is a known enemy of asphalt, as it can weaken the surface and lead to cracks or sinkholes. Quality paving companies design asphalt surfaces with a slight grade to prevent water from pooling. Proper drainage is essential to prevent water from seeping into the base and causing long-term damage.
Pro Tips to Expand the Lifespan of Asphalt Paving
While some factors are beyond your control, many proactive measures can help your asphalt surface last longer. Here are effective tips for keeping your asphalt looking and performing its best for years to come.
1. Regular Sealcoating
Sealcoating is a protective coating over the asphalt to protect it against moisture, ultraviolet rays, chemicals, and oxidation. This not only enhances the look of your asphalt but also acts as a seal that addresses small rips and cracks. The actual recommendation for seal coat application is every 2-3 years, depending on traffic and climate. If you’ve just searched for “paving near me” or “asphalt driveway,” check with local contractors to determine the ideal timing for your area. For example, driveway contractors in Ottawa often recommend sealcoating in the warmer months when it adheres best.
2. Prompt Repairs for Cracks and Potholes
Small cracks can develop into large ones over time, allowing moisture to penetrate and damage the underlying layers of asphalt. Addressing cracks early prevents minor damage from snowballing into expensive repairs. Crack filling is an affordable, straightforward solution that prevents more extensive issues. Driveway contractors often offer maintenance services for minor repairs, and a quick search for “asphalt maintenance services in Ottawa” can help you find local providers.
3. Avoid Chemical Spills
Gasoline, oil, and other automotive chemicals can weaken asphalt by breaking down the bonding agents. If spills happen, clean them up promptly to avoid long-term damage. If you have an asphalt driveway, placing a mat or tray under parked vehicles can help catch leaks and drips.
4. Mind Your Load Limits
Although asphalt is durable, excessive weight can still strain it. For residential driveways, avoid parking heavy equipment or oversized vehicles for extended periods. If you require an asphalt surface for heavy-duty use, consulting with an asphalt company about extra-strength paving options is a smart step.
5. Ensure Proper Drainage
If you notice standing water on your driveway or parking lot, addressing it quickly can save you a lot of headaches. Your driveway should slope slightly to direct water away. If drainage is an issue, consult paving contractors to add inlets or other solutions.
6. Maintain Edge Support
Asphalt edges are vulnerable to breaking when not supported properly. Avoid driving off the sides or placing heavy items close to the edge of your driveway. For high-traffic areas, some contractors offer edging solutions to reinforce these vulnerable spots and prevent deterioration.
7. Consider a Quality Overlay
After several years, you might notice that the surface looks worn but is still structurally sound. Rather than replacing the entire surface, you can opt for an asphalt overlay, which adds a fresh layer on top of the existing surface. This can extend the life of your paving by an additional 10 to 15 years, and is often a more cost-effective alternative to a full replacement.
How Often Should Asphalt Paving Be Replaced?
While asphalt can last up to 30 years with diligent care, there comes a point when repair and maintenance alone aren’t enough. Typical indicators that your asphalt might need replacement include:
Extensive Alligator Cracking: Large-scale, interconnected cracks (alligator cracks) are a sign that the asphalt base has deteriorated.
Significant Potholes or Ruts: If potholes keep reappearing despite repairs, it may be time for a replacement.
Faded Color and Texture: Asphalt’s color fades over time due to sun exposure. If sealcoating doesn’t restore its appearance, the surface layer might be worn out.
If you're unsure whether it’s time to replace your asphalt, consult with “pavement companies near me” for an expert evaluation. An experienced asphalt company can assess the condition and help you weigh the costs of repair versus replacement, considering the current asphalt driveway cost in your area.
The Cost of Not Maintaining Your Asphalt
It’s tempting to skip regular maintenance, but neglecting your asphalt can lead to more frequent and costly repairs. For example, minor cracks can develop into extensive damage that requires full resurfacing. Not maintaining proper drainage can lead to water seeping into the asphalt base, resulting in uneven surfaces and sinkholes. Over time, small issues left unattended can dramatically reduce the lifespan of your asphalt, forcing you to consider expensive replacements far sooner than expected.
Final Thoughts
With the right care, asphalt paving offers an affordable, long-lasting solution for driveways, roads, and parking lots. By prioritizing regular maintenance, sealcoating, and timely repairs, you can extend your pavement’s life, getting more value out of your investment.
