Modular Expansion Joint System (MEJS) Type 6

MEJS is a mechanical device installed in bridge expansion joint openings. The primary function of the MEJS is to allow vehicle traffic to travel smoothly across large expansion joint openings. The MEJS is normally used for expansion joints with a movement range up to 2000mm. MEJS also has the secondary function of protecting the surrounding bridge superstructure and substructure. All MEJS cells are equipped with watertight sealing elements that prevent debris, water and corrosives such as de-icing chemicals from passing through bridge expansion openings and damaging superstructure and substructure components.

Advantages:

• Durable
• Seal can be replaced without disturbing joint
• Low stiffness
• Allows vertical/skew movement
• Seismic movement capability
