Over time, an asphalt surface can become cracked or develop depressions because of exposure to weather, vehicle fluids and the weight of vehicles. If left unattended, the damage only gets worse. Water and other fluids can accumulate in depressions, weakening the asphalt. Fluids can also seep into cracks. Once water seeps below the surface of the asphalt, more damage is inevitable.
Resurfacing—also known as an asphalt overlay—may be a good option for surfaces that are not too badly damaged. An asphalt overlay is a second layer of asphalt applied over an existing asphalt surface. An overlay can be a good solution when the paved surface is damaged but the sub-grade is still in good condition. Before an overlay is poured, existing damaged areas are cut out and patched, depressions are leveled, then a primer is used to adhere the new overlay to the existing asphalt. An overlay that is properly done will look like a brand new asphalt surface. Resurfacing can be an excellent option to repair aged and damaged asphalt, and it’s also much less expensive than having a complete new surface laid.
Contractor’s Asphalt Tip:
An overlay should NEVER be done on a surface that is severely cracked, is crumbling or has spots that are significantly sunken. The new layer of asphalt will simply follow the path of the original layer. Within a short period of time, cracks, defects and depressions will form in the exact same areas as the original surface. When this happens, the surface will be just as damaged as it was before the overlay was applied. It may be difficult to determine whether or not resurfacing will work for your asphalt surface. Call our experienced professionals and ask them to evaluate the project for you. Our paving specialists can determine whether or not an overlay can be used on your surface.
