About Elastomeric Bridge Bearing Pads

In the past, the bridge was constructed from stones or wooden elements. Such a structure having this characteristic can be constructed directly onto the supporting members and the floor slab as well. Furthermore, the structure is used by the current civilization without adequate knowledge of the seismic characteristics of the constructions. When new special materials became available, it was necessary to make constructions to protect against earthquakes (in such a way a variety of supports was invented) and now there are many different kinds of bridges.

Elastomeric bearings are used in most of the construction support work, in which they provide concrete support to transfer the load opposite to the ground. The characteristics of this type of bearing combine several materials and construction properties.

The design of elastomeric bearings has been able to take into account adequate pneumatic pressure to support vertical loads and also has sufficient elastic compressibility to accommodate anticipated deformation. Rubber and steel plates are ideal materials for increasing rigidity and flexibility respectively. In that case, the elastomeric bearings can be strengthened with a soft steel inner plate.

Despite high expectations regarding their performance, elastomeric bearings still require proper deployment instructions. As is widely known, the reinforcement structure of elastomeric bearings allows them to operate under loads of up to 3500 nanometers, with displacement equal to 100 mm, and rotation at 0.04 radians, all of them have a common bending nature.

Custom Sizes and Load Capacities

Each elastomeric bearing pad can be tailored to your project's specific width (up to 600 mm), thickness (12-100 mm), diameter (up to 600 mm for round pads), and length (up to 1000 mm). Load capacities are customized for design requirements, ensuring robust support for small and large bridges alike.

Engineered to Endure Extreme Conditions

These pads demonstrate exceptional resistance to ozone, aging, abrasion, flame, and weather, functioning reliably in temperatures ranging from -40C to +70C. With water absorption less than 1% and high impact resistance, they sustain performance under the most demanding conditions.

High Performance and Compliance

Elastomeric bridge bearing pads meet or exceed major international standards, including IRC:83 (Part II), IS:3400, AASHTO, and BS:5400. Their construction ensures a long service life, minimal maintenance, and safe, efficient load transfer in bridge and structural applications.

FAQ's of Elastomeric Bridge Bearing Pads:

Q: How are elastomeric bridge bearing pads installed?

A: Elastomeric bridge bearing pads are installed by simple placement between the bridge deck and the substructure. Depending on design requirements, they can be bonded with suitable adhesives or allowed to move freely (free-sliding type) to accommodate structural movements.

Q: What is the primary function and benefit of using elastomeric bridge bearing pads?

A: These pads provide a flexible, durable interface that safely absorbs and disperses structural movements, vibrations, and rotations. The result is reduced stress on bridge components, prolonged structural life, and virtually maintenance-free operation.

Q: When should elastomeric bearing pads be used in bridge construction?

A: They should be specified whenever bridges or similar structures require reliable load transfer, movement absorption, and isolation from vibrations. They are suitable for new construction as well as retrofit or rehabilitation projects.

Q: Where can these elastomeric bearing pads be utilized besides bridges?

A: While designed primarily for bridges, these bearing pads are ideal for use in industrial platforms, railway structures, buildings with large columns, and heavy equipment installations-anywhere structural movement isolation and load distribution are crucial.

Q: What materials are available and which should I choose?

A: Pads are available in Natural Rubber (NR) for environments with lower exposure to petrochemicals and in Chloroprene Rubber (CR/Neoprene) for enhanced resistance to ozone, oil, and temperature extremes. Selection depends on the specific environmental and load requirements of your project.

Q: How long do elastomeric bearing pads last, and what maintenance is needed?

A: Under normal working conditions, these pads have a service life of 20 years or more. With high weather and abrasion resistance, as well as minimal water absorption, they require little to no maintenance during their operational lifespan.

Q: What is the recommended storage process for these pads before installation?

A: Store elastomeric bearing pads in a cool, dry place away from direct sunlight, chemicals, and excessive heat. Proper storage preserves material properties and performance prior to installation.
