This study examines two highway bridges constructed using novel fiber-reinforced polymer (FRP) composite stay-in-place formwork and an FRP grillage reinforcement system. Both bridge superstructures rely on the FRP components as bridge deck reinforcement. These bridges were monitored in-situ for a period of five years. The
monitoring included a series of in-situ load test as well as non-destructive evaluation (NDE). Laboratory investigations accompanied and guided the load testing and NDE implemented. Finite element simulations were employed to evaluate the likely causes of premature deck cracking seen in the traditionally-constructed bridge and the FRP-component superstructures. The study identifies sources of potential deterioration, identifies aspects of the bridge superstructures likely to enhance durability, and quantifies the effectiveness and potential for deterioration of the load transfer mechanisms present in the FRP-component superstructures.
