Factory fabricated precompressed water and/or fire resistant tunnel expansion joint systems, and transitions

Abstract

A fire and/or water resistant expansion joint system for installation between substrates of a tunnel. The system includes a coating applied at a predetermined thickness to the substrates and a fire and water resistant expansion joint. The expansion joint includes a core and a fire retardant infused into the core. The core is configured to define a profile to facilitate the compression of the expansion joint system when installed between the substrates. The coating and the fire and water resistant expansion joint are each capable of withstanding exposure to a temperature of at least about 540° C. or greater for about five minutes.
