Rapid Replacement of Four GDOT Bridge Decks

Abstract

The objectives of the research reported in this paper were to monitor and document the rapid bridge deck replacement work of the Georgia Department of Transportation (GDOT) on two bridges in Gainesville, Ga., and two bridges in Atlanta. Documentation of the GDOT work included a time sequence, deck replacement square footage per work period, total construction time, typical work period construction tasks, and photographic display/discussion of the deck replacement work. The precast exodermic deck panel system used by the GDOT provided an excellent means for rapid bridge deck replacement while under staged construction/concurrent traffic conditions. The GDOT work was completed within the imposed time limits while maintaining minimum traffic interruption.
