How to Fix Asphalt Driveway Cracks | Large & Small Crack Repair Guide

Repair small and large cracks in your asphalt driveway with a simple, homeowner-friendly process. This printable quick sheet walks through cleaning out loose debris, blowing the crack clean, using foam backer rod for wider or deeper gaps, applying asphalt crack filler, smoothing the repair, building up low spots, and allowing the material to cure properly before use.

The guide also explains the difference between small hairline cracks and larger gaps, when backer rod is useful, what tools and materials you may need, and the key steps that help improve adhesion and keep water from getting into the pavement.

Important: Use a crack filler specifically made for asphalt and follow the manufacturer’s directions for application temperature, weather conditions, cure time, and when the repaired area can be walked or driven on. This type of repair is intended for maintenance and water control—not for major structural failure, severe base movement, or badly deteriorated pavement.
