Making The Repair

    
    FIVE STEPS TO LONG-LASTING ASPHALT REPAIR

1.  Mark the area to remove.

Crews use paint  to mark the areas to be sawcut. Lines will delineate the inclusion of at least a foot of sound pavement surrounding the damaged area. We use a state of the art diamond blade cut-off saw to make exact and neat cuts to make sure that your repair blends in as smoothly as possible with your existing asphalt.

2.  Prepare the Area.

Remove damaged material to reach a firm base and make certain the remaining material is sound and free of cracks. This step usually involves three operations: (1) cutting to remove deteriorated pavement material, (2) cleaning the area of dirt and debris and backfilling if subgrade is removed, and (3) drying with air or heat to eliminate moisture that would negatively affect adhesion.

3.  Apply tack to sides and bottom.

Immediately before filling, the crew pours tack coat onto the sides and bottom of the area. The tack improves adhesion between the old pavement and the patching mixture.

4.  Install hot asphalt

Install to proper height meeting all surrounding edges of existing asphalt. Asphalt is then compacted using a vibratory plate compactor to inure proper compaction and seal. Compacting reduces the ability of water to penetrate, ties the stones together, and increases resistance to rutting and shoving.

5.   Seal the edges of the patch.

To reduce water penetration and to complete the repair we then use hot rubberized tar that is heated to 350 degrees and applied to all edges of the patch. The tar is molded into the new asphalt and the existing asphalt to insure proper adhesion and form a water-tight seal.
