Potholes occur when moisture penetrates cracks in the asphalt surface of a road or driveway. Cold weather freezes the water and causes it to expand. A pothole forms when dirt and gravel is forced out leaving a hole. The Ice eventually melts and the stressed asphalt becomes a pothole.
Cold asphalt or hot asphalt?
Hot asphalt is mixed around 300 F, and paving, pothole repair and compaction must be performed while the asphalt is sufficiently hot. Paving and pothole repair is restricted to summer months in many states, because in the winter the ground will cool the asphalt before it is packed to the optimal air content, preventing proper pothole repair.
Cold asphalt is mixed and used at lower temperature than hot asphalt. In this state, cold asphalt is easy to work, compact and repair potholes with, and isn’t as viscous as hot asphalt. A well designed cold asphalt takes on the properties of hot asphalt and is virtually indistinguishable from it, despite being easier to use for pothole repair.
