Installation and Performance of Portland Cement Concrete Pavement Joint Sealers
The four cement concrete pavement joint sealers used in the project were: silicone rubber, self-leveling silicone rubber, preformed polychloroprene compression seal, and conventional hot-poured elastic sealant. The silicone rubber sealant was sticky, difficult to install properly, and subsequently, is displaying evidence of increased wear. The self-leveling silicone rubber sealant was more fluid, less sticky, easier to install, obtained the correct depth in the joint most consistently, and has performed extremely well to date. The preformed polychloroprene compression seals appeared to be easily installed. However, uniformity in depth below the surface of the joint was not achieved and twisting of some seals was observed. A greater amount of incompressible materials are collecting in the pavement joints containing the preformed polychloroprene compression seals. The hot-poured elastic joint sealer was easily installed but installers had difficulties controlling the rate of application. It was concluded that the proper construction techniques, successful applications of silicone rubber joint sealers will result. The silicone sealants provide an effecitve means of preventing moisture and incompressible fines from entering the pavement joint.
