Highway Bridge Bearing: The support at a bridge pier carrying the weight of the bridge; may be fixed or seated on.
Highway Bridge Bearing is made of multilayer natural rubber and sheet steel after inlay, conglutinate, vulcanization. It has enough vertical stiffness to support vertical load, and it could deliver the pressure of superstructure to abutment. 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, Rubber 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.
Highway Bridge Bearing is made of multiple layers of rubber sandwiched with and bound to thin steel sheets, and then through vulcanization. The vertical rigidity is sufficient to bear the perpendicular load and to shift the pressure reliably from
the superstructure to the piers. The elasticity of the Highway Bridge Bearing is high enough to suit the rotation of the beam
end. The shear deformation of the Rubber bridge bearing is sufficient to cope with the horizontal displacement of the super structure
