ABSTRACT:
A roadway expansion joint and seal is provided which comprises a pair of parallel metal side rails having a flexible membrane secured therebetween. The membrane includes enlarged opposite side edge portions which are mounted within respective C-shaped sockets in the side rails, and the side edge portions of the membrane each include a cavity which permits the side edges to be assembled in the sockets by initially compressing each side edge portion so as to collapse the cavity, while laterally forcing the same into the socket. Once in position, a relatively incompressible material is injected into the cavities of the side edge portions so as to substantially fill the cavities and thereby resist the withdrawal of the side edge portions from the sockets.
