ABSTRACT:
A sealing system for roadway expansion joint gaps and the like. A continuous seal is provided comprising an elongated central arched segment, a pair of longitudinally extending legs, and a protrusion extending upwardly from each of the legs. The seal embeds at least one fabric reinforcement layer to stiffen, rigidify and strengthen the seal means and the protrusions. The seal is secured to each roadway slab between a horizontal surface and a retainer which defines an elongated recess for sealingly receiving, engaging and compressing a protrusion. A limiter is provided for limiting the compression of the protrusions, and a retainer lip is provided for visually indicating that sealing of a protrusion has been effected.
