摘要：	The first fiber reinforced polymer composite bridge superstructure in New York State was installed in late 1998. These materials are new to bridge applications, therefore no data exists on their inservice performance. A detailed test program of periodic testing and visual inspections was used to monitor its in-service performance, characterize its dynamic properties, and obtain data to calibrate theoretical analyses. This report documents the test program and summarizes the results. The test data indicate that the superstructure is structurally performing well. Several delaminations were found during visual inspections and wearing surface was replaced once. For future applicability of these materials for such applications, these issues affecting the long-term durability of FRP bridge decks should be resolved.
