Abstract:
Full depth structural concrete overlays are commonly used in bridge deck repair and rehabilitation. Beneficial structural effects, such as increase in structural depth, can only be considered in the design if monolithic action of the overlaid slab can be assured beyond the flexural ultimate limit state of the bridge deck. A three phase experimental program to study the effect of different surface preparations and dowels between the "old" deck and the overlay on the overall bridge deck behavior under service loads (monotonic, cyclic, dynamic), overloads and ultimate limit state loads is presented in this report. The three test phases comprised triplet shear block tests, full scale transverse deck slab panel test (simply supported and continuous) as well as the full scale prototype testing of a 60 ft long highway bridge section (Gepford Overhead) which had been in service for 25 years prior to being repaired and tested under laboratory conditions. A complete set of experimental results is presented in this report.
