Crack Sealing

Crack sealing is used for active cracks in asphalt pavements so that water is kept out of the pavements. Sealant installation is affected by a number of factors including: humidity, rout size, crack preparation method, heating time, sealant finishing and protection, and the temperature of air, sealant and pavement.
