Description: Accelerated bridge construction (ABC) often utilizes prefabricated elements to reduce on-site construction times. Prefabricated elements are typically constructed in controlled environments using high-quality materials, so the elements themselves are higher quality and more durable than similar constructed-in-place elements. Because of this, the connections between prefabricated elements will often end up controlling the long-term performance of these bridges. There are many different types of connections that can be used between prefabricated superstructure, substructure, and foundation elements. This session of the workshop gave attendees presentations on connections, materials used in connections (including ultra-high performance concrete), and surface finishes used for connection interfaces.

Royce has led several research projects sponsored by the ABC-UTC and the Oklahoma DOT centered on ultra-high performance concrete and application of other innovative concrete materials to bridge construction and rehabilitation. He works to provide hands-on experiences for the students in his courses and has contributed to several American Concrete Institute efforts to provide resources to university faculty teaching reinforced and prestressed concrete design.
