What is the difference between a temporary and a permanent pothole repair?

A typical permanent repair would see a square or rectangular area cut out of the road around the pothole giving the repair clean straight sides. The hole is cleaned out and painted with bituminous sealant before being filled with a hot bitumen-bound material which is raked and finally compacted.

A temporary repair is a short term measure to make the road safe which involves using a deferred set cold material to fill the hole until a permanent repair can take place. It is not normal to saw cut around a temporary pothole.
