Understanding Your Asphalt Repairs
Contractors Today aids in finding contractor firms and experts in all things asphat. Paving with asphalt is a delicate job that requires the right know-how, patience, technical skills and expertise to perform. Professional contractors should not only offer asphalt paving layering but also repair services when called for. Asphalt paved surfaces have a life span of about two decades. However, potholes, cracks, and scrapes can appear on the asphalt thanks to wear and tear. When such occurs, opt for repair services only from the best. There are different kinds of repair, each which done poorly, could cost you more re-doing them.
Asphalt surfaces are prone to damage especially during the initial year of installation. This could be due to poor paving together with poor maintenance and adverse weather conditions that alter “healing process” of asphalt when it’s new (initial 6-12 months). The chemical composition of asphalt that gives it the viscous property plays a huge role in the level of damage.
Asphalt repairs are specific to the level of damage, the exact location of the damage as well as the client’s budget. There are several types which include:
Skin patching is the method used when damage is only significant on some sections of the asphalt. This method is ideal for repairing potholes, raveling or depressions. It is rather a cost-effective method, used by some as a temporary measure until they can get finances to perform an overhaul. Here, the damaged area is covered using a thin layer of asphalt then compacted to solidify. The technique is a temporary one since the defect is underneath the skin patch. Eventually, the problem will come back to spite you since the skin patch will flake away, but it still remains a great choice for a tight budget.
Cut & Fill
Cut and fill is also known as removal and replacement. It is a high-budget option for instances where the damage is too adverse to simply repair. Under this method, the affected asphalt area is cut-off or removed and the space is dug down in order to add new base, depending on the severity of the situation. The new base is then re-paved using fresh asphalt. This method is expensive but highly effective as the newly filled and patched area won’t develop any problems.
Resurfacing method involves applying a thin top layer of fresh asphalt. This is an ideal method of repairing asphalt that does not have a considerable base failure. Resurfacing extends asphalt’s lifetime as the new 1.5-inch thick top layer protects the layer underneath from damage. This method is by far the most cost effective.
This is also a high-budget method of asphalt repair, but more affordable compared to cut and fill method. Under this method, commercial infrared heaters are used to heat the asphalt paving to temperatures it was when the asphalt was when it was originally laid. The heated asphalt becomes viscous again, clearly showing the deteriorated parts and the ones still rich in asphalt oil. The deteriorated parts are then refilled with fresh asphalt before leveling it out to match the rest of the asphalt. After leveling, the asphalt is then compacted for it to merge with the old asphalt, till it becomes one, almost leaving no sign of repair. The advantage of this is, no saw-cuts are used, and hence no space is left for any water seepage that could cause internal damage. It is also the most eco-friendly repair as the infrared heaters use clean burning and recycled propane to heat the asphalt up. This method is however not offered by most contractors, but you can count on Contractors Today to find for you effective asphalt repair service.
Sealing is a repair method that does more of a preventative role than actually repairing major cracks and potholes. In this method, the seal coat is applied on the asphalt paving. It mostly used to serve or “seal” minor cracks. Sealants, however, have a tendency of reducing the asphalt’s life span, so it shouldn’t be used as an every year solution. Consult your local asphalt contractor on when and how often it is convenient to use sealants.
This method simply involves filling out cracks using crack fillers in order to block any water seepage that could potentially lead to further damage down the line. The crack fillers are done in a way that about 2 – 3 inches of the filler bands over the crack.
