There are different asphalt problems that you might encounter, be it a driveway, parking lot, or roadway. Different problems need different solutions and their own specific repairs. Knowing what kind of problem you have will help guide you to the right repair solution. Once you have diagnosed the problem and decided on the right repair approach, gather up the tools you’ll need. Sourcing the right tools, materials, and team to make the repairs will all come with experience. To help you out, here are some asphalt pavement repair methods you can employ on your next project.
Skin patching is useable for repairing raveling, depression, or potholes. Make sure the area is clean and dry before you start filling holes. An asphalt emulsion also needs application before you start laying a new layer on it. You must make sure that the asphalt is hot, spread evenly, and compacted well in this process.
Some asphalt is so damaged that it’s beyond repair—no amount of patching and sealing will save it. At this point, removing the asphalt completely and replacing it is the only way. Removing the asphalt all the way down to the subgrade (usually concrete) and replacing it with a fresh layer is the best option. The thickness of the asphalt should be enough to withstand the amount of traffic that it will see.
Resurfacing, on the repair scale, is between removing and skin patching. Employ this option when there is no visible damage to the subgrade, but simple taping isn’t enough to repair and protect the pavement. Ensure the surface is clean and dry and then add a new layer of fresh, hot asphalt right on top of the existing layer. This is a cost-effective way for the property owner to get a new pavement without removing the whole thing.
Pavement reinforcement fabric is good when the asphalt is experiencing reflective cracking. The fabrics are specially designed as a moisture barrier and strength booster. The systems provide a waterproof barrier for the subgrade and stress relief for the existing pavement and any asphalt overlay. The extra layer extends the life of the overlay and slows any subsequent reflective cracking.
This isn’t necessarily a repair; it’s more a measure of preventative maintenance for the asphalt. Applying a layer of sealcoat to the existing asphalt protects it from water, ice, salt, road grime, and harmful UV rays. The surface must be debris- and water-free before applying. Fill any holes and cracks beforehand to help the sealcoat adhere better and prevent water from getting to the subgrade.
