• Abstract:
  The Iowa Department of Transportation (DOT) funded a three-phase research project focusing on rapid bridge deck joint repair. Phase I focused on the documentation of current means and methods of bridge expansion joint maintenance and replacement. Under Phase II, a workshop with Iowa DOT personnel, engineers, and researchers identified possible improvements to traditional expansion joint options. From the workshop, a deck over backwall detail was developed that moved the expansion joint away from the bridge deck and instead placed it on the approach slab. This would not only minimize the concrete removal needed for a rehabilitation but would, in turn, prevent deicing chemicals from leaking through the deck joints and damaging the bridge’s substructure. In Phase III, the research team was tasked with the further development of this deck over backwall concept.
