An overlay or resurface can be used on an asphalt driveway, parking lot, or road way. It consists of installing a new layer of asphalt over the existing asphalt and grinding at the transitions (i.e. sidewalks, garages, drains, curbs, or other asphalt points). A paving surface can be deteriorated but still maintain structural integrity in which an asphalt overlay is the proper solution. An existing asphalt surface is the best base for new asphalt. Damaged or troubled areas are repaired before the installation of asphalt. Sometimes all that is required is a leveling course, which is a thin layer of asphalt that is installed to take out any dips or low areas before the finishing course is installed. A tack coat is normally applied on the existing asphalt surface to help the new asphalt adhere to the existing surface. An overlay is usually installed at an average depth of 1.5” to 2” inches thick depending on the project. Overlays are normally cheaper in price and deliver same quality and strength as other asphalt options.
