AASHTO Grade Bearing Pads

AASTHO Rubber Bearing Pads Text Over Bridge

WARCO BILTRITE manufactures a full line of AASHTO Grade Bearing Pads for bridge, building and reservoir construction markets. Rubber bearing pads dampen vibration and permit for the natural thermal expansion and contraction of structures, whether precast concrete or steel, which aids in prolonging their lifespan.

We formulate and mix our own compounds and maintain rigid quality control throughout the manufacturing process to ensure excellent performance and load bearing resistance.

From our AASHTO Grade Bearing Pads, we offer unsupported rubber bearing pads in 50 to 70 (Shore A) durometer, which conform to Cal-Trans 51-1.12H, U.S. Army Corps. of Engineers, American Association of Highway and Transportation Officials (AASHTO) Grade 2 and Grade 3 Standard Specifications for Highway Bridges and M251. Available in Natural Rubber and Neoprene formulations, in rolls 36” and 48” wide in thicknesses up to 1” and in molded forms 36” and 48” widths in lengths up to 30’ (longer lengths available). Custom shapes sizes and lengths are available on a special order basis.

Our capabilities also include 40 durometer neoprene pads in custom sizes for pre-stressed reservoirs that conform to ASTM D2000 M2BC 414 A14 B14 C12 F17.
