Parking Lot Overlays and Patching

Action Asphalt: the Puget Sound Expert in Parking Lot Overlays and Patching

Action Asphalt Paving offers several commercial asphalt paving services to extend the life of parking lots. Most commonly, repairs include asphalt patching and asphalt overlays. If existing asphalt has degraded to the point of potholes or loose “alligatoring” (a cluster of cracked pavement), we recommend patching — removing old asphalt and adding a new layer. In areas where the existing asphalt is still strong, we suggest a fresh asphalt overlay to reinforce the current surface. Applying an engineering fabric with the overlay further extends the asphalt life.

Overlays

When the surface of an asphalt project deteriorates to the point of requiring repairs, an asphalt overlay can be a beneficial alternative to complete replacement.

New asphalt overlays are thin layers (usually 1.5 to 2 inches thick) of new asphalt applied over the existing asphalt surface.

New asphalt overlays don’t require the engineering and planning that a complete installation necessitates, but you should take into account whether the surface requires milling or grading needs to be preserved. Milling removes a basic level of existing material to an appropriate depth before you apply a new layer of asphalt, ensuring the new surface is consistent and smooth for pavement striping.

Patching

Asphalt patching is different from new asphalt installations and overlays in that you don’t alter existing pavement before making repairs. When there is no damage to the base of the pavement, patching can repair the surface of asphalt that is cracked, chipped, loose, or otherwise rough in appearance and texture in order to extend the life of the asphalt by three to ten years.

We use new asphalt patches to improve the surface appearance of pavement and to stop water penetration. Patches are generally 1.5 inches or less in relative thickness.
