Asphalt patching consists of saw cutting existing and replacing failed asphalt. We take care to ensure that all cuts are straight and corners squared. The failed area is excavated/milled to a specified depth, which is at least as deep or deeper than the existing asphalt. The failed material is hauled off-site for recycling.
The existing aggregate base in inspected for proper thickness, gradation and compaction. Typical base repair consist of removal of contaminated aggregate and replacing with fresh DOT certified stone and compacted using vibratory compaction techniques.
We then apply a tack coat to the milled/excavated area. The hot mix asphalt is placed at the specified depths to meet existing grades flush. We also recommend crack filling the seam where the new asphalt meets the existing.
