Plate and Tube Bridge Deck Evaluation in the Deck Test Bed on the Troutville, Virginia, Weigh Station

摘要

This report addresses the laboratory and field performance of multi-cellular fiber-reinforced polymer (FRP) composite bridge deck systems. We focus specifically on FRP decks produced from adhesively bonded pultrusions where the core of the deck possesses a square geometry running transversely to traffic. In laboratory tests, two schemes of loading patches were designed: a steel patch dimensioned according to the American Association of State Highway and Transportation Officials (AASHTO) ridge Design Specifications, and a simulated tire patch constructed from an actual truck tire reinforced with silicon rubber. The stiffness, strength, and failure characteristics of the cellular FRP decks were examined using both loading patches.
