Abstract
An elongated plate of elastomeric material is provided with anchoring means along its side edges for fixedly connecting the same to the sections of the road bed on opposite sides of the gap. Spring means are embedded within the plate transverse to the longitudinal axis and secured at its ends to the respective anchoring means so as to be expanded and/or contracted corresponding to the movement of the road section. The spring means preferably comprise helically wound coils spaced in parallel to each other, transverse to the longitudinal direction of the plate.
