SEALANT APPLICATION can be accomplished in a variety of ways. Twelve methods are outlined in the SHRP publication Materials and Procedures for Sealing and Filling Cracks in Asphalt-Surfaced Pavements. The success of each method is not only determined by configuration but also by cleaning technique and sealant selection. Sealants applied in routed cracks performed longer. A recessed configuration dispenses material into the confines of a routed crack. The sealant can be placed flush with the pavement, slightly below the surface of the pavement or slightly overfilled on the surface. In an over-band configuration, the sealant is placed onto and over an unrouted crack. The sealant can be shaped into a band over the crack using a rubber blade squeegee or a sealing shoe that flattens the sealant over the crack.
