Abstract:
Construction procedures for the rapid replacement of deteriorated bridge decks are described. The paper specifically encompasses the rehabilitation of bridge decks via installation of full-depth precast or precast prestressed concrete bridge deck panels. This system can either be supported on steel stringers or precast concrete girders, and can be very effective in terms of time and cost. The findings associated with this paper are part of a two-year study for the Illinois Department of Transportation. A nationwide investigation is being conducted in an effort to evaluate the structural behavior of this system. As a result, the advantages and disadvantages of the system are being identified, i.e., the reasons for any adverse effects or the good performance of certain aspects of the bridge deck system. Preliminary construction procedures have been established for the rehabilitation of bridge decks using slab units on steel stringers or precast concrete girders. Results of the investigation incorporating these construction procedures have indicated that both systems can be effective with proper planning and execution.
