Chip off loose pavement by placing the point of a cold chisel on the edge of a crack and tapping the other end with a hammer. Work down both sides of the crack, pointing the chisel to widen the base of the crack, and remove debris with a wire brush.
Flush the cracks with water to clean out any remaining dirt and debris.
Measure the depth of the cracks with a measuring stick. Fill any cracks deeper than one-half inch with sand until the crack is half full.
Fill in the remaining hole and any shallow cracks with reinforced vinyl patch compound. Spread it over the gap with a putty knife and tamp it down. Continue to add the compound until it is overfilled.
Use a flat trowel to spread the excess compound over surrounding pavement.
Blend the patches in with the rest of the pavement with tinted sealer. Paint it on with a rolling brush and plan to re-apply the sealer every few years.
