Abstract: Accelerated bridge construction (ABC) techniques were used to rehabilitate two notable bridge structures in the United States in 2016; a 16.5-meter (54-foot) long single-span superstructure carrying U.S. Route 30 over Bessemer Avenue near Pittsburgh, Pennsylvania, and; a 5-span 308-meter (1,011-foot) long historic concrete arch bridge carrying Franklin Avenue over the Mississippi River near Minneapolis, Minnesota. These projects utilized prefabricated bridge elements (PBEs) that were connected together on-site using Ultra-High Performance Fiber-Reinforced Concrete ("UHPFRC"). Different UHPFRC mix designs, supplied by LafargeHolcim's Ductal®, were used for each project. A rapid-set mix used for the Pittsburgh project allowed the single-span superstructure to be replaced during a 57-hour weekend closure, while the Minneapolis project utilized a standard-set mix. In both cases, UHPFRC was used for its ability to rapidly achieve high strength as well as provide simple, strong, durable connections between the prefabricated elements.
