Elastomeric rubber bearing pad is formed by vulcanizing and adhering multilayer rubber sheets and thin steel plates, with enough vertical stiffness, the counter force of the upper structure can be reliably delivered to abutment; and it has better elasticity to adapt to the rotation of beam end; also the bigger shearing deformability can meet horizontal displacement of the upper structure.

Classification and representation methods of elastomeric bearing pads :
(1) Classification as shapes of bridge bearings
a.Rectangular bridge elastomeric bearings
b.Circular bridge elastomeric bearings
(2) Classification as applicable temperature of adhesive varieties of bridge bearings
a.Neoprene bearing(applicable temperature -25~60°C)
b.NR bearing (applicable temperature -35~60°C)
c.EPDM bearing (applicable temperature -40~60°C )
(3) Classification as structure style of neoprene bearing
a.General plate type neoprener bearing
b.Tetrafluoro sliding plate type neoprene bearing.
(1)The plate rubber bearing can elastically absorb the deformation of the upper structure in all directions.
(2)There is no stress concentration in the bearing surface of the plate rubber bearing compared with that of the rectangular bearing.
(3)The plate rubber bearing is easy to be installed, and it can not consider the direction.
(4)Compared with other types of bearings, the plate rubber bearing has low cost and is easy to maintain.
