WILLIAMS AASHTO GRADE NEOPRENE BEARING PADS SPECIFICATION M251-90

Quick Overview

Uses

As economical efficient bearing plates for precast, pre-stressed concrete or steel beams in bridges and buildings. Neoprene Pads permit a smooth and uniform transfer of load from the beam to the substructure, allow beam rotation at the bearing due to deflection of the beam under load. They further allow lateral and longitudinal movement of the beam caused by thermal forces. Neoprene pads have no movable parts and thermal expansion and contraction a absorbed by the pad's ability to give and take in shear. There is no sliding between pad and beam or between pad and abutment.
