Methods for Removing Concrete Decks from Bridge Girders

With ever tightening budgets, states are looking for cost-effective methods of extending the duration from initial bridge construction to complete replacement. One common technique that serves this purpose is to replace the deck after the end of its useful service life has been reached while keeping the original superstructure and substructure. That is, assuming that the superstructure and substructure still have adequate strength and remaining life. For this approach to be successfully accomplished, it is critical that the deck is removed without damaging the superstructure elements. Moreover, as the deck is often removed in large pieces, it is important to prevent concrete from falling below the bridge, especially where a roadway passes beneath. The objective of the work is to determine the most, and/or develop new, cost-effective and efficient deck removal techniques for steel and concrete superstructure bridges. The following criteria will be considered as part of the evaluation: Impact on the future performance of the superstructure, cost, time, safety, and noise. Further, the work will include guidance on assessing and repairing girders that are damaged during removal of a deck.
