Armenia Modular expansion joint

Bridge expansion joints are designed to allow for continuous traffic between structures while accommodating movement, shrinkage, and temperature variationson reinforced and prestressed concrete, composite, and steel structures.There are various types, which can accommodate movement from 30 to 500 millimeters .

Modular Expansion Joint

Modular expansion joint systems are very popular for large joint movements from 160 to 1200mm 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.

Features of Modular Expansion Joint

1.Building height of bridge expansion joint is low, and the structure is simple.

2.Performance of flexible stretch and safety.

3.Easy installation for construction and low price.
