Construction and Performance Monitoring of Innovative Ultra-High-Performance Concrete Bridge

The application of Ultra-High-Performance Concrete (UHPC) materials in rehabilitating bridges and constructing primary bridge components is increasing rapidly across the world because their superior strength durability characteristics when compared to regular concretes. However, there have been few new constructed using UHPC with formworks, ready-mix trucks, construction equipment. This paper presents a comprehensive report encompassing design, construction, performance monitoring Iowa unique technology that includes steel fibers two different lengths embedded concrete. By optimized fibers, both tensile toughness were increased. material was produced local cement aggregates US typical concrete discusses experience gained from design process including mix batching, delivery batch unit, post-tensioning precast slabs at jobsite. For four years after joints decks monitored strain sensors mounted on sides deck joints. values quite similar between each joint, indicating good load transfer girders. A successfully incorporating utilizing truck, has performing satisfactorily post-tensioned girder
