ABSTRACT:
Each of the recessed, confronting edges of adjacent concrete slabs in a roadway or the like has secured therein by a high density reinforced grout an elongated, rigid, prefabricated or precast edger strip, which also has an elongate recess in the edge thereof which faces on the space between the slabs. An elongate, semi-rigid, prefabricated cover member, which is generally T-shaped in cross section, has its upper, plate-shaped section positioned over the upper end of the space between the slabs so that opposite sides thereof project part way into the recesses in the edger strips, and has its downwardly projecting web section embedded in a sealing compound positioned between the confronting ends of the slabs. Remaining portions of the recesses in said edger strips are filled with a low modulus urethane compound.
