Performance Comparison of In-Service, Full-Depth Precast Concrete Deck Panels to Cast-in-Place Decks

项目名称：	Performance Comparison of In-Service, Full-Depth Precast Concrete Deck Panels to Cast-in-Place Decks
摘要：	The use of full-depth deck panels allows for accelerated construction and repair of bridge superstructures, and in some cases decreased overall project costs. These panels have been used for new construction and rehabilitation since 1965. There are several research projects that have been conducted looking into the behavior of different panel and joint details, but there is minimal published work on the performance of in-service full-depth, precast deck panels. The last study looking at the behavior of these panels was conducted in 1995 by Issa, et al.. These researchers surveyed 51 DOTs and determined 13 of them were utilizing or had utilized some type of full-depth precast deck for rehabilitation or new construction. Those responding to the survey highlighted the time savings offered by precast decks. There were some responses that noted leaking, cracking, or deterioration of the joints mainly caused by material quality or the construction procedure. This study did not compare the performance of these full-depth, precast decks with similar CIP decks. There is a major research effort currently being undertaken to investigate the performance of in-service bridges called the Long-Term Bridge Performance (LTBP) Program. The LTBP Program is developing protocols for bridge inspection and evaluation to standardize the assessment of in-service bridges. The LTBP Program has been looking at bridge decks, but their efforts have not included precast panels. Although full-depth, precast decks have been used alongside conventional CIP decks in bridge construction since 1965, there has never been a formal study to determine if precast deck panels behave the same, better, or worse than CIP decks.
