How to patch an asphalt driveway pothole

Use this workflow for a small pothole or a cut-back repair with a measurable area and depth. A narrow crack normally needs a crack filler matched to its width. A shallow worn surface may need a different repair product, and widespread alligator cracking, deep settlement, moving edges, or a hole that keeps returning points to a base or drainage problem.

Check the product limits before buying. For example, QUIKRETE Asphalt Cold Patch is intended for potholes and cracks wider than 1 inch, at a total depth of 1 to 3 inches, with an approximate maximum repair area of 3 by 3 feet. Those are product-specific limits, not universal rules for every cold patch.

Remove loose, broken edges first, then measure the length, width, and average finished depth of the repair. For an irregular pothole, use the longest and widest practical dimensions and allow for the tapered or broken edges instead of measuring only the narrow opening at the top.

Enter the compacted yield printed on the bag or technical data sheet. QUIKRETE lists about 0.32 cubic feet from a 50 lb bag, while other products publish different coverage. The asphalt patch calculator converts the measured volume, adds your allowance, and rounds the result up to whole bags.

Wear the safety equipment required by the product and tools. Sweep out loose asphalt, dirt, vegetation, and debris. Remove standing water when the instructions require it, and expose a firm base. Square or cut back weak edges only when the selected product calls for confinement and you can use the tools safely.

If the hole extends below the asphalt layer, rebuild and compact the missing base before placing the surface patch. Do not keep filling a deep, soft, or waterlogged cavity with bagged patch. Repair only pavement you are authorized to maintain; public-road potholes should be reported to the responsible agency.

Follow the selected product rather than a generic lift rule. QUIKRETE specifies 1-inch lifts so each layer can be compacted before the next is added, then calls for the loose material to finish about 1/2 inch above the surrounding pavement before final compaction.

Compact the full patch, especially the edges, until it is firm and level with the driveway. FHWA field research found that a properly compacted throw-and-roll repair can be cost-effective when quality material is used, but a residential product label still controls the application details for that product.

Observe the product's traffic and sealing times. QUIKRETE advises avoiding dry steering on the patch for at least 24 hours and waiting at least 30 days before applying driveway sealer; another product may give different instructions.

After rain, check whether water collects beside the repair or enters surrounding cracks. If the patch sinks, pushes out, or breaks apart again, stop repeating the same surface fix and have the base, drainage, and extent of failed pavement assessed.
