Is Cold Patch or Hot Mix Asphalt Better for Pothole Repair

Hot mix asphalt repair is the only long-term pothole fix that will prevent the pothole from resurfacing again. The hot mix method entails first removing the asphalt around the pothole, essentially creating a bigger hole. This hole is then filled in and sealed using hot asphalt. This prevents water from being able to penetrate around the patch
