The National Center for Asphalt Technology (NCAT) study* on longitudinal joints has determined that Crafco Pavement Joint Adhesive is the winner for reducing longitudinal joint cracks and joint failure over all other joint sealant products and techniques tested. The studies took place over a six-year period (Sept. 1995 - July 2001) and were performed in five states: Pennsylvania, Colorado, Michigan, Wisconsin, and New Jersey. These tests confirmed that longitudinal joints in asphalt pavement, if not treated, would encounter cracking, raveling and eventually fail due to water infiltration, thermal movement and low density. They have found that Crafco's hot-applied modified asphalt composition effectively bonds paving passes together creating a watertight seal during thermal movement resulting in improved long-term performance of the joint with no significant cracking. This product is also effective for waterproofing exposed edges of asphalt concrete pavement areas such as at the curb gutter, and shoulder interfaces. Additionally, waterproofing can be assured where manhole covers and hand valves (gas, water, etc.) are installed in asphalt concrete pavement. Like other Crafco products this product is easy to apply using Crafco's Melter/Applicator equipment.
