What Is Bridge Bearing
A bridge bearing is a component of a bridge which typically provides a resting surface between bridge piers and the bridge deck. The purpose of a bearing is to allow controlled movement and thereby reduce the stresses involved. Possible causes of movement are thermal expansion and contraction, creep, shrinkage, or fatigue due to the properties of the material used for the bearing. External sources of movement include the settlement of the ground below, thermal expansion, and seismic activity.

Rubber used in the composition of bearings can be either natural (NR for “Natural Rubber”) or synthetic, in which case the compound is generally a chloroprene polymer poly-chloroprene or CR for “Chloroprene Rubber”.
A laminated elastomeric bearing is a “block of vulcanized Elastomer reinforced internally by one or several steel plates, chemically glued (bonded) during vulcanization. Elastomer is a macromolecular material that regains its shape and initial dimensions approximately after being submitted to significant deformation under the influence of a low stress variation”.
