DCEG - Strip Seal Expansion Joint With Sinus Plate

The use of “sinus plates” reduces the noise from over-rolling traffic by up to 80 % by covering the straight transverse gap in the carriageway. The wheels of over-rolling vehicles thus maintain constant contact with the expansion joint’s surface, eliminating the noise caused by impacts with the gap edge. The special shape of the sinus plates also enables motorcycles and bicycles to cross the joint safely. DECG expansion joints featuring sinus plates are ideal for use on bridges near residential areas or in other noise-sensitive zones.
