Full-Depth Asphalt Patches

A full-depth patch repair distresses of medium to high severity, such as alligator cracking, corrugation, depression, oil spillage, rutting, swelling, edge cracking, bumps and sags, and existing patches. A partial-depth patch is used to maintain/repair low and medium severity distresses, such as corrugations, depressions, rutting, shoving, slippage cracking, swelling, and existing patches. Full-depth repairs involve the removal of the complete pavement down to the subgrade or to an intermediate base or subbase layer that is intact. Partial-depth repairs usually involve removing the failed asphalt surface, excluding the base course, and replacing the surface layer with a hot asphalt plant mix.
