II Introduction of rubber bridge bearing
Natural Rubber bearing generally consists or interleaving layers of rubber bonded sandwich fashion to steel plates.The whole unit is covered with rubber to afford weather protection. A bridge basically consists of bridge deck supported by piers.In order to avoid over stressing and Damage by movements of vehicle and loading to the piers, bridge bearings are used to accommodate these movements so as to reduce the reaction forces and bending movement to within the safety limits of structure.Natural Rubber is an ideal engineering material for bridge bearings as it is highly elastic and sufficiently soft to accommodate these movements without transmitting harmful stress and also it can absorb and isolate energies from impacts and vibrations.
III Types of rubber bridge bearings
• Laminated bearings - an elastomeric bearing containing steel laminates bonded to rubber • Plain pad bearing - a plain rubber pad containing no steel plates • Strip bearing - a plain pad bearing for which the length is much greater than the width (>10 times) • Pot bearing - a bearing consisting essentially of a block of solid rubber enclosed between a metal Piston and metal cylinder
IV Advantage and performance of rubber bridge bearing
1 Fine technical performance 2 simple structure 3 low price 4 no maintenance 5 easy to change 6 buffering and shock isolating 7 low building height Elastomeric rubber bridge bearings shall be composed of multiple laminates of elastomeric material separated by steel reinforcing the overall size of the bearings the number of laminates and thickness of laminates are designed in accordance to the requirement of load to be transferred.Bearings having steel plates as reinforcement shall be cast/compression molded / vulcanized as single unit in a mold under pressure and heat.
V Applications of rubber bridge bearing
General elastomeric laminated bearing suits to bridges with span less than 30m and small displacement.Tetrafluoro elastomeric laminated bearing suits to bridges  with large span,several spans. According to the performance characteristics of neoprene, it is mainly used in flame retardant products, oil products, weather resistant products, adhesives, etc., for example, building waterproof sheet, building sealing strip, highway caulking material, bridge bearings gaskets, low-voltage wire and cable sheathing, all kinds of sealing products, anti-corrosion lining, adhesive and so on
VI  Manufacturing Process of rubber bridge bearing
• 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
VII Testing of Neoprene Bridge Bearings
In house Quick Production Test of all bearings shall be done at Clients/Representative presence.Tests confirming to AASHTO specification in accordance with Acceptance Testing on either Level I or Level II or Short/Long-Duration Compression Test up to 10000 kN with horizontal shear up to 600kN can be carried out in our facility.Test specimens shall be in accordance with ASTM D 3182 or D 3183.Where test specimens are cut from  finished product, a 20 percent variation from the original physical properties is allowed.3rd party witnessing of these tests are also done in our facility as there are no independent laboratory in middle east with such capabilities.
(Important you need) Laminated Bearing designing:
Our technical and design team can design right type of bearing based on loads provided  design bearing for end applications.On receipt of corbel size, load and movement details of  requirements, calculations and bearings sizes can be provided based on results on parameters .
