Once the asphalt pavement have cracks, if we don't repair it on time, maybe the asphalt pavement have more strictly disease. Water is the most destructive element to our pavement. Water entering asphalt pavement through cracks accelerates the deterioration of the asphalt pavement. In time, the water will undermine and weaken the asphalt pavement base material creating cracks and potholes. Crack sealing can prevent water from entering the base and subbase will extend the pavement life from 3 to 5 years.
Pavements expand and contract with seasonal temperature changes. Consequently, cracks and joints are expanding and contracting when the pavements move. Sealing the cracks with flexible
rubberized asphalt that bonds to the crack walls and moves with the pavement will prevent water intrusion.As part of a Pavement Management System, crack sealing can reduce pavement
deterioration by restricting water penetration into underlying base and subbase layers. This restriction helps to maintain pavement structural capacity and limits future degradation. Simply stated, sealing cracks and joints in pavements extends the service life of the surface treatment and the pavement.
