A standard asphalt overlay consists of a new layer of asphalt applied over the existing asphalt surface. The thickness of an overlay is typically 1 1/2 to 2 inches, but type and amount of traffic, as well as individual customer needs, are also considered.
The vast majority of potholes and pavement failures can be traced to water entering the base and sub-grade through joints that have not been crack sealed in both concrete and asphalt. In most pavements, the base, sub-base or sub-grade consists of a material that loses its load-carrying capacity when wet.
