Most potholes form in late winter and early spring when rain or snow melt gets into cracks and other defects in the pavement. When this moisture freezes, the resulting pressure causes the pavement to break and fail. Over time, this freeze/thaw cycle (contracting and expanding) can cause the pavement to crack, which can cause the pavement to deteriorate quickly under the weight of traffic. As the temperatures swing between freezing and thawing happens more frequently, the number and size of the potholes increases. Visit the Minnesota Department of Transportation's website to learn more about how potholes form.
Pothole patching on city streets is done year round. Patching in the winter and spring months is done with cold mix asphalt, which is more workable at cold winter temperatures, but not a permanent repair. Regular city pothole patching with hot mix asphalt begins in May when asphalt plants re-open for the season. Hot mix asphalt is more durable than cold mix asphalt and provides a more permanent repair of potholes.
