Development of Specifications for High-Performance Fiber Concrete for Nevada (NDOT 366-16-803)

Bridge decks are the weakest link among the various bridge components, lasting approximately 30 years. According to the American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) specifications, a bridge deck should be expected to last for 75 years. Bridge decks are exposed to excessive traffic and chloride elements. The chloride elements can seep through cracks within the bridge decks, causing corrosion in the steel. High durability concrete has been used to improve the serviceability of structures. High-performance fiber concrete (HPFC) that is used in the construction of bridge decks, longitudinal connections, and transverse connections can significantly improve the service life of a bridge deck by reducing premature distresses. The purpose of this research is to determine the most effective applications of HPFC in order to optimize both structural performance and economic efficiency, and to investigate whether HPFC can be produced with locally available materials to include batching and placing methods within the state of Nevada. The fiber types, dimensions, dosage, design requirements, material, and construction specifications need to be developed to allow the Nevada Department of Transportation (NDOT) to successfully implement the use of HPFC.
