A freeze thaw cycle causes potholes. Water in a crack will freeze and expand during the winter, weakening the pavement. When it thaws and the water evaporates, a cavity is left. As vehicles drive over the weakened cavity the pavement begins to crumble and a pothole appears. The more traffic on a pothole the faster it grows.
