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.

Abstract: An expansion joint adapted to overlie and sealingly close an expansion gap between roadway bridge sections or the like and comprising an elastomeric membrane having an upstanding arch disposed across the gap. The arch has a corrugated configuration with the corrugations thereof extending laterally across the gap to impart substantial flexibility to the membrane so as to accommodate relative movement of the roadway sections in each of the vertical, longitudinal, and lateral directions. Side rails overlie the side edges of the membrane and anchor the membrane between the road sections.
