| Abstract | Ultra-high performance concrete (UHPC) is being adopted for a variety of different bridge construction and rehabilitation applications. In North America, the most popular application of UHPC in bridge construction is for field-cast closure pours between adjacent prefabricated bridge elements, which are employed in many accelerated bridge construction (ABC) projects; this application has proven to be a common entry point for many bridge owners. As the demand for this innovative class of materials increases, so will the need for knowledge regarding the material properties and material characteristics. To fill this knowledge gap, researchers at Federal Highway Administration’s (FHWA’s) Turner-Fairbank Highway Research Center (TFHRC) executed an experimental study on six different commercially-available materials being marketed as “UHPC-class”. The goal of the research was to provide the bridge engineering community with a more comprehensive set of properties for this class of materials, which in turn could facilitate broader use within the sector. The UHPC-class materials were evaluated using 14 different ASTM, AASHTO, or FHWA-TFHRC-developed test methods. Results indicate that these materials behave similarly with respect to some performance measures such as compressive strength, tensile strength, and durability, but vary with respect to others such as dimensional stability, bond to precast concrete, and compressive creep. |
