[PDF] AN EXPERIMENTAL STUDY OF ELASTOMERIC BRIDGE BEARINGS …

Recent AASHTO specifiions have placed a nuer of restrictions on the use of elastomeric bridge bearings. Elastomeric bearings with tapers built in to accommodate span end elevation differences were disallowed by the most current specifiions even though no previous research into elastomeric bearing performance has included tests on tapered pads. The purpose of …
