Asphalt driveways and parking lots are essential parts of our everyday infrastructure, providing smooth, durable surfaces for vehicles and pedestrians. However, like any other material, asphalt requires regular maintenance to remain in top condition. One of the most effective ways to extend the life of your asphalt surface is through sealcoating. But how do you know when sealcoating is needed? In this blog post, the experts at Andersen Asphalt & Striping will explore some key indicators to help you determine the right time to sealcoat your asphalt.
Fading Asphalt Color
One of the most visible signs that your asphalt needs sealcoating is a noticeable change in color. Fresh asphalt has a deep black hue, but over time, exposure to sunlight and the elements can cause it to fade to a grayish color. This fading indicates that the asphalt’s binder, which holds the aggregate together, is breaking down due to UV radiation and oxidation. Sealcoating can restore the original color and provide a protective layer against further damage.
Small Asphalt Cracks & Surface Wear
Asphalt is subject to wear and tear from vehicle traffic, weather conditions, and chemical spills. If you start to notice small cracks, surface erosion, or raveling (where the aggregate begins to come loose), it’s time to consider sealcoating. These minor issues can quickly escalate into larger problems if not addressed promptly. Sealcoating fills in small cracks and forms a barrier that helps prevent water from seeping into the pavement, which can lead to more extensive damage.
Potholes & Larger Pavement Cracks
While sealcoating is not a solution for severe damage like potholes and large cracks, their presence indicates that your asphalt surface is in need of maintenance. Before sealcoating, any significant damage should be repaired. Once repairs are made, sealcoating can help protect the new patches and extend the overall life of the pavement.
Frequency of Use
The amount of traffic your asphalt surface receives plays a significant role in determining when sealcoating is needed. High-traffic areas, such as busy parking lots and driveways, will require more frequent sealcoating compared to less-used surfaces. Generally, it’s recommended to sealcoat every 2-3 years for high-traffic areas and every 3-5 years for low-traffic areas. Regular inspection can help you gauge the wear and tear and schedule sealcoating accordingly.
Age of Asphalt Pavement
The age of your asphalt surface is another important factor. New asphalt should be allowed to cure for at least 6-12 months before the first sealcoat application. After the initial sealcoating, a regular maintenance schedule should be established based on the factors mentioned above. As asphalt ages, it becomes more susceptible to damage, so staying on top of sealcoating can help prolong its lifespan.
Weather Conditions
Weather conditions can significantly impact the condition of your asphalt. Areas with harsh winters, heavy rainfall, or intense sunlight will require more frequent maintenance. Sealcoating before winter sets in can help protect the asphalt from freeze-thaw cycles, which can cause cracking and other damage. Similarly, sealing in the summer can protect against UV damage and oxidation.
