The rubber pad bearing is designed to transfer the pressure from the superstructure to the pier and bear the bridge deformation. The bridge rubber bearing has large vertical stiffness to guarantee less deformation under the largest vertical load. The rubber bearing features good flexibility in horizontal direction to adapt to the horizontal displacement of the bridge caused by braking force, temperature, contraction and creep of concrete and load effect. The rubber pad bearding can also withstand the rotation of beam end.
A variety of rubber pad bearings are available in Duratech:
Rectangular pad rubber bearing; circular pad rubber bearing; chloroprene rubber baring (working temp. -25～ 60℃), natural rubber bearing (working temp. -35～ 60℃); EPDM rubber bearing (working temp. -40～ 60℃)
