Anotácia

This specification covers the material requirements for preformed polychloroprene elastomeric joint seals for concrete pavements. The seal consists of a multiple web design and is installed with a lubricant. The seal functions by compression of the seal between the faces of the joint with the seal folding inward at the top to facilitate compression. The seals shall be preformed, and the material shall be vulcanized elastomeric compound using polychloroprene as the only base polymer. The materials shall also comply with the physical properties prescribed herein such as tensile strength, elongation, hardness, oil swell, ozone resistance, low-temperature stiffening, low-temperature recovery, and compression deflection.
