Abstract

A device for bridging over expansion joints of a roadway includes a matting of elastomeric substance placed over spaced elements of a joint to bridge the same. The matting has longitudinal portions held in grooves provided in retainer profiles positioned along the edge of each element of the joint. The longitudinal portions of the matting have ribs which fit into the grooves of the retainer profiles and fill the grooves so as to leave an anchoring space between the bottom of each groove and the ribs. The matting has holes which connect the upper surface of the matting with the anchoring space. The holes are filled with elastomeric synthetic resin casting which also fills the anchoring space.
