Mill & Patch Asphalt Patching Repair process MN
As Minnesota’s leading commercial paving contractor, many of our projects restore and repair asphalt surfaces. Tightly alligatored and raveling blacktop require the mill and patch repair 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 blacktop surface.
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.
Skin Patch Repair Process
The skin patch process, just as the name sounds, entails applying a thin layer of blacktop. It is used to build up low areas prior to applying an overlay or seal coat. It is primarily used to resolve water flow issues or to minimize ruts and uneven asphalt prior to the next procedure.
Allied crews clean the area to receive the new skin correction. Clean surfaces bond together better and last longer.
After cleaning, CSS1H tack material is applied.
Finally, Allied crews patch the area with the required thickness, typically 1 to 2 inches for a skin patch.
