Bearing Pads

Bearing Pads are often used to enhance the performance of prestressed/precast concrete structures. The purpose in design for using bearing pads is to uniformly distribute loads over the bearing area, absorb impact and to permit limited horizontal and rotational movements between two structural members, while providing stress relief in these areas. Additional characteristics are their ability to expand and contract, absorb vibration and shock to reduce the destructive action between moving and stationary prestressed/precast members.

X-CORD™ Random Oriented Fiber Pads (ROF) are preformed fabric bearing pads that are composed of cross-layered, bi-directional reinforcing fibers. This is a composite material comprised of elastomer with reinforced randomly oriented fibers. The use of fibers strengthens the elastomers stiffness to resist vertical loads while increasing capacity, but soft enough to allow shear deformation.

Isoflex™
cotton duck pads are reinforced bearing pads that are used when a higher compressive strength is needed. These pads are reinforced with horizontal layers of fabric, bonded in the elastomer. Designed with a high load capacity (10,000 PSI), Isoflex™ Pads are used to control shock and vibration and create a uniform bearing area. This material conforms to AASHTO Section 18.4.10.1 Grade III and MIL-C-882E

Neopads™ (Neoprene Bearing Pads) are made of 100% chloroprene and is the only material that fits the requirements of AASHTO, Section 18 Standard Specifications for Highway Bridges. For compressive stresses lower than other pad types, Neoprene Bearing Pads allow for the most freedom of movement at the bearing point. It is important to identify that chloroprene pads that don’t meet AASHTO Specifications are not recommended for use under any concrete and/or steel commercial structural member. Available in 50, 60 and 70 shore “A” Durometer hardness.
