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.
