Abstract:Full-depth, precast concrete deck panels have been heavily used in bridge construction since the 1970’s. The use of these panels has traditionally been thought to both accelerate construction and improve the long-term durability performance of the bridge deck. While many engineers and academia are intrinsically aware that confined precast can perform equally or better than non-confined, cast-in-place concrete, evaluation between the two has never been studied holistically. The main objective of this project was to determine the in-service performance of full-depth, precast concrete (FDPC) deck panels compared to conventional cast-in-place (CIP) decks. The secondary objective is to determine successful and problematic details for these members. A survey was developed and distributed to state DOTs. Survey responses were used to develop the FDPC Deck Panel Database. Results from the DOT survey and analysis of the FDPC Deck Panel Database are discussed in this report.
