ASTM D8138-23 PDF

Scope: 1.1 This specification covers the material requirements for preformed silicone joint seals for bridges. The seal consists of a silicone rubber gland preformed to a continuous length. Its design shall prevent any tension from occurring in the seal or bonding point during normal movement. The seal is installed by bonding it to the joint header with a silicone-based adhesive and is designed to seal the joint, preventing liquid intrusion. 1.2 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 all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
