All types of highway bridge concrete expansion joints

All types of highway bridge concrete expansion joints

We produce various of highway bridge concrete expansion joints including modular expansion joints, finger type expansion joints, elastomeric rubber bridge expansion joints and bitumen/asphalt expansion joints, they are used on highways and briges to reduce the vibration and pressure from the various of traffic tools when they pass through, in this way to protect the highways and bridges.

Applications

 A) Modular highway bridge concrete expansion joints are manufactured to match perfectly the structure’s profile, enabling surface water to remain on the deck so that it can be directed toward the drainage systems designed for this purpose.

The primary function of the Modular Expansion Joints is to permit vehicle traffic to travel smoothly across large expansion joint openings. It does this by dividing the large expansion joint openings into a series of smaller openings called cells. These cells work in series to accommodate the necessary thermal bridge movement (expansion and contraction) while providing a smooth riding surface for bridge vehicle traffic. The Modular Expansion Joints is normally used for expansion joints with a movement range exceeding 75 mm.

B) Sliding finger type highway bridge concrete expansion joints are suitable for use under heavy traffic, and mainly applied to the device with 20-320mm expansion. Their special doweled connection system makes them particularly useful where the impact on the main structure should be minimised. The system is designed on a modular basis, allowing individual finger plates to be quickly replaced as required. Finger type joints are still specified on many bridge projects due to proven long-term structural performance. These joint systems are also convenient to install on bridge rehabilitation projects requiring a shallow joint depth and/or staged construction.

C) Elastomeric rubber highway bridge concrete expansion joints are applicable to old bridges, small bridges, and those with low load capacity. 

D) Bitumen/Asphalt highway bridge concrete expansion joints is suitable for the roads and bridges joints with not more than 50mm movement.
