ABSTRACT

Nonproprietary ultra-high performance concrete (UHPC) has been developed, tested, and implemented in the field for bridge components using materials local to New Mexico (NM), United States of America (USA). Nonproprietary UHPC has superior characteristics similar to commercially available UHPC products. Recent research has focused on applying the nonproprietary UHPC in various structural applications including bridge superstructures, overlays, and connections. Bridge 9706 located in Anthony, NM, USA, was recently constructed with two simple supported spans, using nonproprietary UHPC in one span, and high performance concrete (HPC) in the second span. Design compressive strengths for nonproprietary UHPC and HPC were 145 and 65.5 MPa, respectively. Load tests were conducted on the bridge to evaluate the behavior of the locally developed UHPC girders in direct comparison with the HPC girders. This paper compares the measured strains from the external transducers and load distributions between the UHPC and HPC girders from the load tests.
