Asphalt failures and fixing potholes are common all over America. There are many types of asphalt failures. Potholes are one of the most major concerns and are formed when water gets under the pavement and to the surface through cracks in the asphalt. The water loosens the sub-base, freezing moisture in the winters, causing frost hauls. When the frozen moisture under the asphalt thaws out and melts, you are left with nothing but avoid. The asphalt and weight of cars sink themselves into this void, causing asphalt cracking and ultimately a pothole.
