EVALUATION OF JOINT SEALANT MATERIALS
In May, 1968, the Department's Research and Development Section initiated a project to evaluate joint sealants being marketed for use on roads and bridges. In the study, representatives of 31 companies installed 46 products primarily on one road and one bridge for evaluation. Highway research engineers evaluated the materials' properties and the field performance of the joint sealants. The investigators concluded that: (1) transverse joints in roads and bridges can be effectively sealed through proper design, construction and selection of materials, (2) of the sealants tested neoprene compression seals performed best in the transverse pavement joints and in the bridge expansion joints, (3) three pourable sealants (two polyurethanes and the one polyvinyl chloride material) performed effectively in the field, (4) the asphalt-based sealants did not adequately seal joints that experienced movement, (5) many pourable sealants performed well in the laboratory but experienced mixing and application problems in the field, (6) lubricant adhesives enhanced the performance of neoprene compression seals, (7) the best approach to forming pavement joint reservoirs appears to be the removable or permanent inserts, (8) periodic cleaning and resealing of transverse contraction and expansion joints is both necessary and cost-effective.
