Made of Chloroprene (Neoprene) Rubber. The most common type of structural bearing used on highway bridge is the elastomeric.
Elastomeric bearings protect the structures when relative movements occur between adjacent structural members by preventing the transmission of harmful forces, bending moments and vibrations.
Elastomeric Bearing Pad comes in two types; Plain Bearing Pads that are simple rectangular blocks of rubber and Laminated Bearing Pads that have thin horizontal steel plates embedded at specific intervals within the elastomer.
