摘要

Research is ongoing at the Constructed Facilities Center-West Virginia University in terms of developing better fabric architecture and manufacturing process (pull-speed, wet-out time, die temperatures, die length, and degree of cure), leading to enhanced performance. The goal is to reduce the weight of FRP composite deck and hence the cost, while satisfying the demands of highway bridge loads and affects of harsh environments. Bridge deck deterioration has been recognized by highway agencies to be one of the most complex problems of the infrastructure. Federal and State highway agencies have turned to investigating non-conventional materials to help solve the deterioration of the highway infrastructure. Fiber-reinforced, polymer (FRP) composites are one of the advanced materials considered to have high potential for use in bridge deck repair or replacement. The use of an innovative, FRP composite structural shape for bridge decks is presented in this paper with emphasis on its development, laboratory testing, field implementation and field testing.
