ABSTRACT:
A roadway expansion joint and seal is disclosed which comprises a pair of parallel metal side rails having a flexible elastomeric membrane secured therebetween. The membrane includes enlarged opposite edge portions which are solid in cross section, and which are mounted within respective C-shaped sockets in the side rails. The edge portions include a recess in the outwardly facing surface thereof and which defines a pocket between the edge portion and the inner wall of the C-shaped socket. The recess is sized and positioned to permit the edge portion to laterally flex to facilitate assembly thereof into its associated socket, and also, the pocket is adapted to be filled with an adhesive material to securely maintain the assembly of the membrane and side rails. In addition, the membrane includes a central web portion which is configured to accommodate relative movement of the side rails.
