Description of bridge bearing:
Elastomeric rubber bearings provide vibration isolation for application where structure
movements, longitudinal, transverse and rotational are too small to moderate. These are
available in strip form or as plain pads. Laminated types, consisting of rubber layers
separated by vulcanised steel plates, provide a robust bearing for larger structures and
can also be configured in sliding types.
Features of bridge bearing
4. Manufacturing Process
• Preparation of rubber compound according to specification required
• Preparation of steel plates
• Application of bonding agent to steel plates
• Assembly of compound and plates
• Compression moulding
• Performance Test
• Ready for installation
5. Bearing Load Testing.
Neoprene Bearing Pads, neoprene bridge bearings, laminated elastomeric bearings,
seismic isolators etc are generally known as bridge bearing pads in Construction industry
manufacture them in our purpose built plant using high-grade virgin Neoprene - Polychloroprene Grade- 2 into a rubber compound to match AASHTO M 251 Specification under controlled heat and pressure.
Manufacturing of laminated bearings are done by many a rubber moulding companies around the world but to evaluate that these bearings will confirm with Vertical Load and lateral shear capabilities as specified by designer. The only way is to test these bearings under real time load to ascertain deflection on vertical load and subject to tests to evaluate stress strain relation ship under lateral shear under own eyes or witnessed by a qualified 3rd party Engineer.
