GFRP Reinforced Barrier Curbs

Glass Fiber Reinforced Polymer (GFRP) reinforcement has recently drawn tremendous amount of interest in engineering practice. Years of research together with successful pilot implementation projects have provided confidence to engineers for field implementation of GFRP in bridge structures. Since the first steel-free deck used by Missouri Department of Transportation (MoDOT) in 2007, both Carbon Fiber Reinforced Polymer (CFRP) and GFRP bars have been used in 4-5 bridge decks on the state bridge system. These previous efforts along with the reduced prices have promoted potential implementation of both steel-free deck and barrier. However, MoDOT currently does not have specifications for using GFRP reinforcement within barriers, which will be developed in this proposed project.
