The proliferation of prefabricated bridge elements and systems (PBES) over the past four years has led to a recognition among owners and specifiers that robust connection systems are a key part of any successful bridge construction project. Ultra high performance concrete (UHPC), a steel fiber reinforced cementitious composite possessing exceptionally high mechanical strength and durability properties, can facilitate simplified, effective use of PBES. Field casting of UHPC connections between prefabricated components results in a strong connection, and it frees the owner from concerns regarding the short- and long-term performance of the connection. The mechanical properties of UHPC allow for redesign of common connection details in ways that promote both ease and speed of construction.
