  • Pothole Repair: Cold Patch vs. Hot Asphalt Repair ...

    Cold patch repairs are “quick fixes” and do not properly fill or seal a pothole, which means that damage to the asphalt will continue to occur. Eventually, areas repaired with a cold patch will end up forming into potholes again. With hot mix asphalt repair, the pavement around a pothole is excavated. Then, it is filled in and sealed with hot asphalt.
