Modular Expansion Joint, Bridge Expansion Joint



Modular Expansion Joint Systems have gained overwhelming worldwide acceptance for accommodating and sealing large joint movements on bridge structures. By incorporating the results of recent research activities, each joint system is designed to provide watertight, fatigue resistant, long-term, maintenance-free performance.



Design Principles



Fatigue Resistant

Modular expansion joint assemblies are subjected to millions of high dynamic stress cycles due to passing vehicle loads. Recognizing the significance of these dynamic loads on the long-term performance of expansion joint systems, Haider became the first China company to introduce fatigue-resistant design principles to modular expansion joint assemblies. It is strongly recommended that a specification which includes fatigue design provisions be included in the contract documents.



Watertight Integrity

Each Modular Expansion Joint System not only bridges the joint gap but also protects the structure from premature corrosion. Design of the strip seal sealing element is based on compression of the neoprene seal lug into the gland recess of the centerbeam and edge beam. This mechanically-locked neoprene seal not only provides excellent watertight characteristics but also achieves high pullout resistance.
