ASTM D3542-08 (R2019) PDF Download

The ASTM D3542-08 (R2019) standard outlines the requirements for the material used in preformed polychloroprene elastomeric joint seals for bridges. These seals are designed to be installed between the faces of the joint and function by compression, with the seal folding inward at the top to facilitate compression.

The purpose of these seals is to effectively seal the joint and reject any incompressible materials. To ensure quality and performance, the standard specifies certain physical properties that the materials must conform to. These properties include tensile strength, elongation, hardness, ozone resistance, low-temperature recovery, high-temperature recovery, and compression-deflection properties.

It is important to note that this specification may not be applicable for seals whose height is less than 90% of its nominal width. This standard provides a framework for manufacturers, engineers, and other stakeholders involved in bridge construction to ensure the quality and performance of preformed polychloroprene elastomeric joint seals.
