How to Properly Repair your Asphalt Driveway

Is your asphalt driveway in need of repair? Are there patches of asphalt missing, potholes and cracks running through it? Repairing asphalt is relatively easy. Here’s how:


The pothole you’re planning to patch must have edges that are vertical. You can’t pour cold patching material into a depressed area of asphalt and expect it to be permanent. It will only break up again. Make the edges of the pothole vertical and crisp because they act as a retaining wall for materials used for patching.


Be sure to remove all loose debris from the pothole once you have made all edges vertical. If the bottom of the hole is not clean, patching will only be temporary. Any hole deeper than two inches requires crushed stone to be used as fill before coarse asphalt is added.


To make a compact base in the hole, use a 4 x 4 steel tamping tool. Do not use rounded gravel as a base. Only crushed stone that is angular in shape should be used.


Proper thickness for asphalt patches is between 1 ½ and 2 inches. If you install asphalt to a depth greater than 2 inches, it will take longer to cure and the repair may not be successful.

Compact Patches

Never seal a compact patch. Once you’ve installed the patch material, use a steel tamping tool to tamp down the cold patch material. Check to ensure the surface is level and there are no low spots. You must wait at least 30 days before sealing, as the patch will take that long to completely cure.

Sealing Edges

When your patch has thoroughly cured, seal the edge between the old and new asphalt with a high performance crack filler. Apply the crack filler using a ½ inch paintbrush to be certain that the crack is bridged evenly.

Filling Cracks

As the water in crack filler evaporates, it will settle somewhat. Fill the crack level, allow it to cure and refill it, being certain to bridge the crack evenly. If the crack is deep, fill it with coarse, dry sand before applying the crack filler.
