Potholes are an act of nature.
Moisture falls into the cracks in pavement and freezes and expands the crack. Traffic pounds the pavement and breaks down the asphalt or concrete. It didn't take long for the constant freezing and thawing to create some fairly large holes. To make winter-time repairs, street crews use a special mixture that works in cold temperatures, but is a lower grade than a summer mix. The city uses a semi-permanent repair method.
