Standard Specification for Preformed Silicone Joint Sealing System for Bridges
STANDARD published on 1.5.2023
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers the material, manufacturing, and physical requirements for preformed silicone joint seals used in bridges. The seal consists of a silicone rubber gland preformed to a continuous length and is designed to 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, sealing the joint to prevent liquid intrusion. Physical requirements for the preformed silicone joint seal gland cover resistance to accelerated weathering, tensile strength, elongation at break, hardness, tear strength, compression set, and heat-aged properties, whereas physical requirements for the silicone-based adhesive cover tensile strength, elongation at break, sag/flow, tack-free time, resistance to UV, and cure through to 1/4-in. thickness.
