A Look At Repairing Asphalt Potholes With Cold And Hot Patch
A pothole in your asphalt driveway or parking lot can become a serious matter. The hole is more than just an ugly eyesore. It poses a tripping hazard for your guests and that can result in a personal injury situation. In addition, rain will puddle in the hole and lead to further asphalt damage as well as damage to the base. You might be able to fill small holes yourself using cold patch material, but you may need an asphalt contractor to repair big holes or holes surrounded by crumbling. Here's how asphalt repair might be done.
Repairs With Cold Patch
Cold patch is easy for DIY repairs since you don't have to worry about heating the patch material. You do need to clean the sides of the hole by breaking off crumbling pieces and leaving solid asphalt in place. Once that's done, you can fill the hole with sand and gravel and then tamp it down to make a stable base for the patch. Buy asphalt cold patch from the hardware store and pour it into the pothole. Tamp it down so the patch is compacted and level with the surface of your driveway. Cold patch can be used in a wide range of temperatures and weather conditions, and it hardens quickly so you don't need to rope off your lot or driveway after using it.
Repairs With Hot Asphalt
Filling a pothole with hot asphalt requires more work and special equipment. Hot asphalt may be needed when there is a lot of damage that needs to be repaired, such as crumbling near the hole. Some asphalt companies have mobile asphalt recycling trucks that can turn chunks of old asphalt into hot mix to use for the repairs. The asphalt contractor may decide to use a saw and cut out all the damaged pieces so there will be no crumbly chunks left to worry about. Then, a heat panel is lowered over the area to heat up the existing asphalt so the hot mix will blend in seamlessly. When the surface is ready, the heated asphalt is spread out evenly over the damaged area and the hot mix is added and leveled. The final step is to use a roller machine to compact the hot asphalt so the surface is level.
If the pothole is in a parking lot, you'll probably want repairs done by a contractor who can check for other damage at the same time. It's good to have a paving contractor you work with regularly so repairs can be done in a timely manner to prevent trip and fall incidents on your property and to keep the driveway in good shape for as long as possible.
