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.

1.1 This specification covers the material requirements for preformed polychloroprene elastomeric joint seals for concrete pavements. The seal consists of a multiple web design and functions only by compression of the seal between the faces of the joint with the seal folding inward at the top to facilitate compression. The seal is installed with a lubricant and is designed to seal the joint and reject incompressibles. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Note 1: This specification is a manufacturing and purchasing
specification only and does not include requirements or
considerations for selection of size, or the installation of the
joint seals. However, experience has shown that successful
performance of this product depends upon the proper selection of
size and cross-sectional design of the joint seal, joint size, and
joint spacing for the ambient conditions the pavement will be
exposed to, and care in the installation of the joint
seals.
