ABSTRACT:
An expansion joint adapted for sealing an elongated gap formed between two adjacent road sections. The joint provides a continuous support for vehicles crossing the gap while enabling the desired temperature responsive movement of the slab road sections. A pair of non-metallic elongated mounting strips are secured to the adjacent road sections on either side of the gap. An elongated seal strip is mechanically and adhesively secured between the spaced mounting strips for straddling the gap to exclude entry of undesired matter into the gap. A curable epoxy cement is employed to form a smooth transition vehicle support surface between the road sections and the seal strip.
