Asphalt paving can be a worthwhile investment for your home, as it can enhance the beauty of the exterior and provide a neat and easily maintainable surface for your driveway. However, asphalt can be susceptible to damage over time, so regular maintenance and repairs are needed to ensure the surface stays intact and appealing. Here is a look at frequently asked questions on asphalt paving to help you better care for your paved surfaces and hopefully increase their lifespan.
Why is seal coating important?
Asphalt is essentially a porous material that can sustain damage due prolonged exposure to direct sunlight, snow, and ice. Pooling water, oil spills, or even antifreeze can also degrade the asphalt surface, making it susceptible to water infiltration and fading.
Seal coating basically protects the surface from oxidation caused by sunlight and seals the surface from infiltrating water, helping to prevent damage and fading. Before seal coating your driveway, be sure to clean it with a stiff broom so as to remove debris and stains that may prevent the sealant from adhering to the surface properly. You should then use a squeegee to apply the sealer to the driveway, ensuring you cover every inch of the surface so as to offer proper protection to your investment.
Why are there texture variations?
Typically, asphalt contractors use a paving machine to apply and spread asphalt over your driveway and sidewalks. However, there are some areas where the machine can't effectively spread the asphalt due to its size. This means that sections along walls or on narrow walkways have to be spread and raked manually using a squeegee.
Areas done by hand tend to have a slightly different texture to areas done by machine. This is usually normal and shouldn't be a cause for concern. As the driveway ages, the areas with different texture will usually become less noticeable.
What is the difference between a prime coat and an overlay?
A prime coat is typically an application of low viscosity asphalt that is spread over the stone base course that acts as the foundation of your paved surface. The prime coat serves to strengthen the base course, preventing the erosion of gravel and stone that would eventually weaken the entire paved surface. The prime coat also helps the top pavement layer to adhere properly to the base course, increasing the structural integrity of the entire paved surface.
An overlay on the other hand is a layer of hot mix asphalt that is applied on an existing paved surface to fix damage such as extensive cracks and fading. The overlay will often make the surface smooth and more aesthetic, helping to prolong the life of your asphalt paving.
