845. What effect does ice have on potholes? - AH
Water and ice are major contributors to potholes. When water flows into cracks in the road and then freezes, it tears the roadway apart. That's because ice takes up more room than the water from which it's formed—ice is less dense than water. Since the water expands as it freezes, it enlarges the cracks that contain it and gradually breaks up the roadway.
