The state-of-the-art of fiber-reinforced polymer (FRP) composite stay-in-place (SIP) structural form systems for bridge decks is presented in this paper. This technique involves constructing a concrete deck whereby prefabricated FRP components act as both the permanent formwork and the bottom flexural reinforcement. The advantages and limitations of the technology are presented, along with the current progress of experimental and analytical investigations. Extensive laboratory investigation is presented covering numerous aspects of the system, including strength, fatigue, and environmental performance. A variety of system configurations are discussed. Examples of field applications are presented, along with evaluations of cost effectiveness and inspection considerations. The result of these investigations show that FRP SIP formwork systems can be both constructible and meet applicable code requirements for strength and serviceability. Preliminary cost assessments suggest that increases in material costs can be partially offset by savings in labor during installation. Finally, future research needs are identified.
