Many Allied projects restore asphalt surfaces. Tightly alligatored asphalt and raveling asphalt require the mill and patch process prior to an overlay or seal coat. At times, some tightly alligatored areas, usually where the asphalt is very thick, do not require any patching prior to an overlay or seal coat.

The mill and patch process may also be used to resolve water flow issues. Occasionally, no milling is required prior to cleaning, tacking, patching, or leveling the underlying asphalt.

In low, cracked or deteriorated areas, asphalt is milled to a level that will integrate the patch or overlay with adjacent concrete gutters, loading docks and miscellaneous structures.

Excellent preparation is the key to a great result, so the Allied team always thoroughly cleans the milled surface area to ensure adhesion. CSS1H tack material is then applied to glue the two layers together.
