We are the regions related to the slab and side abutments of a bridge, the slabs of a bridge, or while they are going; They are concerned with movements such as sitting, use, comfort, fatigue and contraction. Expansion joints make these uses suitable for one use.

Modular expansion joints meet these gaps by dividing them into several gaps separated by steel beams. The gaps between these beams are covered with rubber gaskets that make them waterproof. The modular expansion joint center beams are supported by the support beam covering the bridge gap. With the control system of the expansion joint, the traffic loads are compensated for the total movement between the divided spaces of the expansion joint. 

AR-EX Single Span Expansion Joints are designed according to the motion demand in the bridge design.
