Potholes are mostly caused by soft base or sub base under the pavement. As the weight of cars and trucks pass over the weak spot in the road, pieces of the pavement weaken, which causes the material to break down from the weight, creating alligated areas which eventually turns into a potholes. Water entering into the sub base is one of the main reasons the sub base can become weak. Some potholes start from the surface and can form due to petroleum spills or improperly installed asphalt. Asphalt installed cold or too thin can lead to a pothole

The first step of determining how to fix the pothole is determining its cause. Once the root cause is established the border around the weak or alligated area of asphalt is sawcut , the asphalt is removed, and at this point the base can be replaced or bladed and shaped to desired level. Once the pothole is prepped and edges have been cleaned Hotmix or coldmix asphalt can be installed. Smaller potholes are repaired by dumping asphalt into the pothole and leveling with lutes and shovels and Larger potholes can be repaired using a asphalt laydown machine.
