Professional Asphalt Repairs

Partial-Depth Asphalt 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. Partial-depth patch procedural steps are identical to full-depth patch. The one exception is that when saw cutting the pavement, control the patch depth to only allow cutting to the depth required for the repair. Furthermore, removal of the material in the area is usually performed with a cold milling or cold planing device. If the material has delaminated from the layer below, a light-weight jackhammer (10 to 17 pounds) and/or a shovel or equipment bucket may be used to remove the material from the repair area.

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.
