Effectiveness of Neoprene Seals in Preventing Concrete Pavement Contraction Joint Deterioration
Over 200 cores were taken from contraction joints sealed with compressible seals on 17 construction projects over a period of four years in order to determine the amount and rate of deterioration of the concrete at the bottom of the joint. Seal performance was rated, chloride content of concrete was determined, and drainability of base material was rated. The study indicates that the neoprene seals are performing well in preventing the entry of incompressibles but permit the entry of liquids into virtually all joints is occuring, but at a relatively low rate for most projects. The data indicate that most of the deterioration occurred during the first five years and shows little significant change for the following years. Several modifications in design, construction, and maintenance of concrete contraction joints are suggested.
