Step 1: Clean Crevices

Clean both crevices and the driveway. Use a stiff brush to remove any loose material from the crack. Clean the surface with a garden hose.

Step 2: Apply the Patch

For large cracks, apply an asphalt patch made of a mixture of coal tar pitch, sand, clay and water. Use a trowel to apply the patch (Image 1). For small cracks, use a putty knife to apply asphalt caulk (Image 2).

Step 3: Apply Sand and Press

Pour sand over the patch to reduce its stickiness. Then drive over the patch with your car to press the material into the asphalt. The patch should cure within 24 hours.

Tip: Don't apply an asphalt patch when the outside temperature is below 50 degrees Fahrenheit.
