ABSTRACT:
An expansion joint seal for use in roadways, bridges and the like adapted for use with a pair of elongated, parallel spaced-apart edge members defining a gap therebetween and each of the edge members having a generally C-shaped cavity opening towards said gap. The seal includes mounting beads on each of its longitudinal edges for reception within the aforesaid edge member cavities and a double walled, resilient web construction spanning the aforesaid gap and being attached to the mounting beads. The double walls of the web are disposed in an upper and lower relative relationship to one another and are connected to the mounting beads at correspondindly upper and lower portions thereon. The upper and lower web walls fold downwardly upon movement of the edge members towards one another and corresponding reduction in width of the gap. The upper and lower walls are connected to one another by a pair of downwardly extending struts which cause the upper and lower walls to fold in a desired manner while also providing additional strength to the configuration. The upper wall is surmounted by an inverted, V-shaped crown which folds upwardly away from the downwardly folding upper wall upon compression of the seal. The upwardly folding crown portion thereby functions to eject incompressibles out of the gap and/or to preclude the disposition of incompressibles in the gap.
