AbstractThis paper introduces three laboratory tests for evaluating the interfacial bonding of bituminous sealants to pavements. The first test incorporates a surface energy approach to calculate the work of adhesion for each pair of sealant-substrates. The second test can be used to rank different pairs of sealant-substrate based on their maximum load, Pmax and required energy to failure, E. The third test is a blister test used to determine the sealant modulus and the interfacial fracture energy (IFE). Tests were conducted using several sealant types and three aggregate types, and laboratory results were correlated with the actual field performance for the sealants evaluated.
