This tutorial will show you how to patch cracks in your asphalt driveway. Cracks and potholes form due to the freezing and thawing of snow and ice, weed or grass growth in small cracks, and general wear and tear. Regular maintenance will prevent the need for major repair work or having to replace your drive. The best way to begin is to repair any existing cracks or potholes. This is easy to do and requires up to a day to complete depending on the condition and size of your driveway. It is also a good idea to prepare to sealcoat by patching all the existing cracks.
