The Arizona Department of Transportation (ADOT) is looking to develop a successful, non-proprietary formula for mixing ultra-high-performance concrete (UHPC). It wishes to have such material available for Accelerated Bridge Construction (ABC) bridge closure pours due to its durability, ductility, strength, and fast set-up, curing, and strength gain. ADOT wishes to join Federal Highway Administration (FHWA) and other organizations to develop non-proprietary, and therefore more economical, UHPC mixtures that stand to accelerate its bridge projects. |
