Features of rubber bridge bearing:
(1) Quality materials including natural rubber, neoprene complying with AASHTO standards.
(2) Allow for expansions and contractions of precast steel structure of bridges.
(3) Capable to control load distribution, meanwhile accommodate thermal and end-beam rotational movements.
(4) Vibration, sounds and shocks isolation.
(5) Avoid excessive load eccentricity and edge compression.
(6) Simple but robust structure.
(7) Lower price than laminated elastomeric bearing.
(8) High cost effectiveness.
(9) Minimal maintenance is needed
