When this happens potholes slowly over time begin to form. Repeated exposure to traffic and normal daily use of a roadway, driveway, or parking lot will help to facilitate the formation of potholes. Pothole repair is a strategy offered by asphalt companies as a way to remedy the problem. First, the pavement surface is cleaned and hot tac oil is applied. Finally, the pothole is filled with asphalt mix and compacted. This type of repair can be expected to last.
