Bridge bearing pads are structural elements used in bridge construction to support and distribute loads between bridge components. They are typically placed between the bridge deck and its supporting structure, such as piers or abutments.
These pads serve several purposes:
1. Load Distribution: Bridge bearing pads help distribute the weight of the bridge and traffic loads evenly across the supporting structure, preventing concentrated stress points.
2. Movement Absorption: They accommodate movements caused by thermal expansion, contraction, and settlement, allowing the bridge to flex and move without causing damage.
3. Vibration Dampening: Bridge bearing pads can also reduce vibrations caused by traffic or environmental factors, enhancing the comfort and safety of bridge users.
Bridge bearing pads are commonly made from materials such as elastomeric rubber, neoprene, or reinforced concrete, depending on the specific requirements of the bridge and its location. They come in various shapes and sizes to accommodate different load capacities and movement ranges.

 

 

Bridge bearing pads are manufactured under different standards and codes of several organizations like BRITISH STANDARD, AASHTO, and EUROPEAN NORMS.

 

In Pakistan, the NHA has given a different set of standards according to those bearing pads that have been tested. These standards are as follows
