A "Pothole" is a hole in the street with the bottom of the hole shaped like the bottom of a pot (rounded).
Potholes are formed when asphalt ages, it becomes more porous, allowing rainwater and melting snow to penetrate the surface. In cold weather, the water that has drained through to the foundation freezes to form pockets of ice; the ice expands and warps the pavement. When the temperature rises above freezing, the pockets of ice melt and leave voids beneath the road surface. The unsupported pavement collapses under the weight of the traffic resulting in potholes. The pothole expands as traffic continually hits the hole.
The material used to repair potholes does not stick as well to the surrounding pavement when it is cold or wet outside. Repairs made during the winter may/will not last as long as repairs made to dry, warm pavement. We cannot wait until warmer weather to repair the potholes as the potholes must be repaired for safety reasons.
Potholes are sometimes called kettle and known in parts of the western United States as a chuckhole.

Hot asphalt patching takes skill to work the hot asphalt with a rake. It needs to be leveled and has to be the right thickness. It is extremely hot when it is first applied. Hot asphalt remains flexible so it can be worked into the repair area. Hot asphalt is usually carried in an asphalt hot box. A hot asphalt box is insulated and heated to keep the asphalt mix hot. This allows the asphalt to remain workable. Without asphalt hot box, the asphalt would cool too quickly and turn to a solid form which is why the use of hot asphalt during the winter months may not be feasible.
Cold patch, also known as cold mix or cold asphalt, is a way to make road repairs quickly because it can be applied right from the container without heating. It can be used with little or no preparation work. It is simple to work with. Cold patch can be applied under all weather conditions. Cold asphalt also does not require any special skills, heavy rolling machines, or special applicators as it can be shoveled or poured into a pothole and tamped down with a hand tool. Cold asphalt patching material also freezes and becomes hard during the winter months. Repair crews must often use a tiger torch (portable torch) to heat the cold patch material in order to make it pliable when the temperature goes below freezing.
