A summary of six years experience using FRP composites for bridge decks

Though fiber reinforced polymer (FRP) composites have been used in other industries for years, their use for highway bridge decks is relatively new. Over the past six years, however, approximately 83 bridges have been built or rehabilitated with FRP decks. Since all of these were designed and constructed without the benefit of nationally accepted standards, there are varied lessons to be garnered from these projects. This paper summarizes the experience of state agencies, presents some case studies, and, based on this information, suggests when the use of FRP decks is most appropriate.
