Repair a cracked driveway by filling cracks with asphalt patch, then coat the surface with a blacktop refinishing compound, available at hardware stores. For a more involved project, consider upgrading your driveway with a decorative border of concrete or paving stones.
How are potholes created? Potholes occur when moisture penetrates cracks in the asphalt surface of a road or driveway. Cold weather freezes the water and causes it to expand. A pothole forms when dirt and gravel is forced out leaving a hole. The Ice eventually melts and the stressed asphalt becomes a pothole.
