Frost wedging causes potholes to form. Water gets into the cracks and over night the water freezes. Water expands in the crack and in the morning it melts. The process goes on over and over again forming a pothole.
This is called Freeze-Thaw Weathering

Freezing and thawing cycle that causes potholes in roads and breaks in rocks?
Freeze/thaw cycle doesn't create potholes. It creates cracks on pavement. Potholes form when water, whether from melting snow, rain or frost thawing gets into the cracks in the pavement and cause the road base to shift and develop voids just under the pavement. When this occurs, the weight of vehicles causes the pavement to crumble causing potholes.
