摘要

The expansion joint (1), between two construction sections (5) e.g. of a highway, is a thermoplastic profile with two mounting points (2) at the ends at the constructions, and take up any forces. A distorting section (3) is between the mountings to take up any movements. Each mounting point has an upper surface (8) to extend the road surface (6) at the constructions. The ends of the joint are held in place by rigid bars (4) with in longitudinal recesses (7).
