Water and/or fire resistant tunnel expansion joint systems
First Claim
1. A fire and water resistant tunnel expansion joint system, comprising:
- a fire resistant coating applied at a predetermined thickness to achieve a substantially uniform layer on substrates of a tunnel; and
a fire and water resistant expansion joint including;
a compressible core having an edge, wherein the substantially uniform layer of the coating extends along the substrates of the tunnel to the edge of the core; and
a fire retardant material infused into the core in an amount effective to pass UL 2079 testing, the core configured to facilitate compression of the expansion joint system between the substrates;
wherein the core has a compressed density of between about 160 kg/m3 to about 800 kg/m3; and
wherein the coating and the fire and water resistant expansion joint are capable of withstanding exposure to a temperature of about 540°
C. at about five minutes and are adapted to pass the UL 2079 testing.

Abstract
A fire and/or water resistant expansion joint system for installation between substrates of a tunnel. The system includes a fire resistant coating applied at a predetermined thickness to achieve a substantially uniform layer on the substrates and a fire and water resistant expansion joint. The expansion joint includes a core having an edge, wherein the substantially uniform layer of the coating extends along the substrates of the tunnel to the edge of the core, and a fire retardant infused into the core. The core is configured 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.
