RAPID BRIDGE DECK REPLACEMENT WITH FULL-DEPTH PRECAST CONCRETE SLABS

In an attempt to expedite the construction process for deck replacement projects, the Connecticut Department of Transportation investigated a design that would use full-depth precast concrete deck slabs. The idea was to limit the amount of form work and casting of concrete done in the field. There were no standard details or methods for a precast slab bridge deck, so the department researched the subject to develop a knowledge base. The process that the Connecticut Department of Transportation underwent to research past studies with precast bridge elements is outlined. The research included laboratory studies as well as actual construction projects in several states. Using the results of the research, the Connecticut Department of Transportation developed a system that met the objective. This was a case in which information from several research efforts in the past was compiled into a working system that was structurally sound and practical. The system was tried on two distinctly different bridges with different approaches to rapid deck replacements. The first involved a fast-tracked full closure of a ramp with a one-lane bridge, while the second included a long viaduct that could be closed only on weekends. Both projects were a success and have been in service for several years without any problems.
