ABSTRACT:
A seal having an elongated body including a mounting portion extending along its longitudinal edges for securement to a pair of spaced-apart structural members defining a gap therebetween in an expansion joint assembly. The seal has an intermediate expansion portion formed integral with the mounting portion and having an upper treadway surface formed with at least three integrally connected corrugated members each having a central, substantially planar surface and a pair of inclined legs extending downwardly and outwardly to form a substantial V-shaped groove at the joinder of adjacent legs, the outermost legs being integrally connected to the mounting portions. A lower expansible section is formed with at least two laterally spaced protuberances and an integral connecting section joining the protuberances. A plurality of nonintersecting struts connect the V-shaped junctures of the corrugated upper treadway surface with the lower expansible section substantially at the junctures between the protuberances and the connecting section. Additional struts extend downwardly and outwardly from the upper treadway surface to the lower expansible section adjacent the junctures between the intermediate expansion portion and the mounting portions.
