During the winter months, asphalt pavements are subjected to traffic, moisture penetration and in many area of city, repetitive freeze-thaw cycles. Under traffic loads, the more brittle colder pavement and the moisture trapped in the pavement base often lead to the formation of potholes, normal repair these problem not choose Crack Sealing Machine.
Methods for repair of a pothole vary, they include:
Throw and roll—the hole is filled with a cold mix material and compacted using the tires of the maintenance truck, which Crack Sealing Machine is not repair it.
Edge seal—the cold mix throw-and-roll patch is sealed around the edges with an asphalt based sealant material by Crack Sealing Machine pouring.
Semi-permanent—the pothole is properly milled to square edges and is patched with cold mix, or in some cases, hot mix. It is compacted using a steel drum or rubber tired roller
Even with a properly constructed cold mix patch, a pothole is likely to fail before the pavement is resurfaced or rehabilitated. Further exacerbating the problem, is limited manpower availability to do the patching and the impacts to the traveling public when the highway is partially closed for pothole patching. To maintain an acceptable pavement ride quality, ensure motorist safety and to minimize vehicle damage, potholes must be filled more efficiently and effectively.
