Bridge Elastomeric Bearing Pads: The “Invisible Cornerstone” Fortifying Transportation Arteries

In bridge engineering, elastomeric bearing pads serve as the critical link between superstructures and substructure piers. Like the “joints” of a bridge, they silently bear enormous loads and mitigate various external impacts, directly determining the bridge’s safety and service life. With over a decade of experience in the bridge component sector, our high-performance bridge elastomeric bearing pads have become the preferred choice for key domestic and international bridge projects, thanks to their superior quality and professional services.

The core advantages of our products stem from exceptional materials and craftsmanship. We use a composite formula of natural rubber and chloroprene rubber, refined through a high-temperature vulcanization process, endowing the bearing pads with both ultra-strong compressive resistance and elastic recovery capability. When bearing loads exceeding 5000kN, the deformation remains within 5%, effectively distributing the weight of the beam; in the face of high-frequency vehicle vibrations, over 70% of vibration energy can be attenuated through their damping properties, reducing structural fatigue damage. Meanwhile, the addition of special anti-aging additives allows the products to operate stably in environments ranging from -40℃ to 80℃, with salt spray and acid-alkali resistance far exceeding industry standards, making them suitable for complex scenarios such as coastal areas, plateaus, and chemical industrial zones.

Customized services precisely meet diverse needs. Tailored to the distinct characteristics of highway bridges, railway bridges, and municipal bridges, we provide full-process technical support: for highway bridge projects, we can customize highly elastic bearing pads to adapt to dynamic loads from heavy-duty trucks; for railway bridges, we optimize stiffness design to ensure smooth train operation; for municipal overpasses limited by space, we offer ultra-thin stiffened plate-type bearing pads. During the construction of Wuhan Yangsigang Yangtze River Bridge, we customized extra-large bearing pads with a diameter of 1.2 meters based on its double-deck design, perfectly meeting the 6000kN load-bearing requirement and ensuring stable operation after the bridge opened to traffic.

A rigorous quality inspection system safeguards product quality. Starting from raw material warehousing, each batch of rubber undergoes tensile strength and aging resistance tests; during production, vulcanization temperature and time are monitored in real-time; in the finished product stage, 12 tests including compression tests and displacement measurements are conducted, fully complying with standards such as ASTM D4014 and GB/T 26743. In the maintenance project of Qingdao Jiaozhou Bay Bridge, our bearing pads successfully passed project acceptance due to complete inspection reports and up-to-standard performance parameters, effectively resolving the deck settlement issue caused by aging of the old bridge’s bearings.

From river-crossing bridges to urban overpasses, our elastomeric bearing pads have served over 200 projects nationwide. Choosing us not only grants access to suitable, high-quality products but also comprehensive services including technical consultation and on-site installation guidance.
