The best method for pothole patching and repair is to use a combination of hot asphalt mix and cold patch material. The hot asphalt mix is heated to 300°F, then applied over the area with a trowel or squeegee. The hard patch material can be used as an overlay on top of the hot asphalt mix, providing additional stability and durability. The two materials should be layered together in multiple layers until they reach the desired depth. This method ensures that the repairs are done correctly and last longer than other methods, such as simply filling holes with gravel or sand.
