PRECAST CONCRETE COMPOSITE DECK COMPONENTS FOR REHABILITATION OF BRIDGES
The first part of this paper provides a brief review of the critical issues met in replacing deteriorated bridge decks with precast deck systems, drawing on existing papers published by PCI and ACI. Recommended practices for typical bridge rehabilitation projects are provided. The second topic focuses on the rehabilitation of the Tappan Zee Bridge over the Hudson River near New York City. Results are presented for an experimental program conducted on a 10 m (33 ft) span full-scale lightweight concrete slab-steel beam composite bridge deck unit. Loading history included 10 million cycles of flexural fatigue loading, followed by a flexural load capacity test. Measured values of capacity and mid-span deflection at this ultimate load level are compared with simplified analytical predictions.
