Elastomeric bridge bearings are crucial components in the construction and maintenance of bridges. They provide support and flexibility, allowing for movement and load distribution, ensuring structural integrity and longevity.
Elastomeric bridge bearings consist of layers of elastomeric material, such as natural rubber or neoprene, bonded to steel plates. They act as a cushion between the bridge deck and substructure, absorbing shock and vibration. The elastomeric material exhibits high compressive strength, resilience, and resistance to environmental factors.
