Utilization of UHPC Bridge Superstructures in Texas
The use of ultra-high performance concrete (UHPC) in Texas bridges has the potential of producing substantial improvements to bridge construction. For example, the recent Malaysian experience with UHPC proved the fact that bridge superstructure weight can be reduced by 40 percent. For long-span bridges, such self-weight reductions can result in significant design and construction benefits. Within this context, this projects aims to identify the applications in which the use of UHPC can be leveraged to develop new structural systems. Objectives of this project are to: (1) conduct an analytical feasibility study to identify the material properties for which a non-proprietary UHPC mixture design should be developed to deliver the optimal design benefits; (2) develop a non-proprietary concrete mixture design to meet the needs identified in Technical Objective 1; and (3) conduct full-scale and material-level experiments to study long-term mechanical properties in an effort to eliminate or minimize the use of ordinary reinforcing bars in UHPC applications.
