　　crack sealantWhat is the significance of repairing road cracks?

　　Cracks often appear on urban roads. According to the causes of crack formation, these cracks are mainly divided into two types: one is structural damage cracks caused by driving loads; Another type is structural damage caused by driving loads. The other is the surface temperature of asphalt. Temperature cracks caused by changes, including non load cracks in low-temperature shrinkage cracks and temperature fatigue cracks. The reflection cracks of semi-rigid base asphalt pavement are non load type, caused by temperature changes, and in some cases may also be caused by a combination of temperature and load.

　　However, as long as these cracks are dealt with in a timely manner, the operation is relatively simple and there is no need to worry about glue (highway sealant). Usually, the type of crack is destructive crack. This is because asphalt concrete pavement has structural damage, namely "surface" damage, and can only be excavated and treated for maintenance work similar to foundation pit repair. The second type of crack, namely reflective crack, belongs to "line" damage when it appears. Seize the opportunity, immediately fill the cracks, and firmly connect the original asphalt concrete pavement to form the tensile effect of elastic expansion joints. The intrusion of rainwater (snow) and debris on the road surface slows down the speed of road damage and achieves preventive maintenance. Otherwise, the cracks will continue to expand with the intrusion of rainwater (snow) and debris, and develop into a type of destructive crack. As a result, it can only be excavated and treated, and the foundation pit can be repaired, which affects the huge maintenance costs of flat highways.

　　Therefore, by slotting and cleaning cracks, filling and repairing with road sealant, the sealant is firmly connected to the original asphalt concrete pavement and forms a tensile effect of elastic expansion joints, thereby sealing the road. Surface rainwater (snow) invades water and debris, slowing down the speed of road damage, reducing roadbed damage, and achieving preventive maintenance.
