Project description

The earliest phases of this project date back to 1998, when research was initiated to identify effective & cost efficient design & construction strategies & procedures for rapid rehab or replacement of bridge decks, to include those decks which must be r/r-ed under conditions of concurrent traffic. Phase 1 consisted of identifying & analyzing the various strategies for such work, and making recommendations on which are the most appropriate for the specified conditions. Phase II consisted of monitoring & documenting the rapid replacement work on four Georgia DOT bridges in the Atlanta metro area; identifying design & construction problem areas, as well as corrective actions that should be taken to eliminate these in future rapid deck replacements. Phase III will consist of construction of two test bridges on I-59 in Collinsville, AL using two different types of rapid deck replacement technologies. Phase IV will consist of evaluating the structural performance of the decks constructed in Phase III. Phases III & IV have essentially been halted indefinitely due to delays in letting the construction project.
