Field Issues Associated with the Use of Fiber-Reinforced Polymer Composite Bridge Decks and Superstructures in Harsh Environments

Abstract

There has been ample time for the United States to evaluate the use of fiber-reinforced polymer (FRP) composites to serve as bridge decks and superstructures under real-world environmental and operating conditions. This provides a great opportunity to weigh in on the decision to move forward with these materials. By studying the successes and failures, materials and techniques used for the design and construction of these bridges can be improved so that we can move closer to the goals of maintenance-free bridges and service lives exceeding 100 years. Though only a few of these structures are instrumented for structural health monitoring, there are a sufficient number of lessons that can be gleaned from the experiences of various owners during the fabrication, installation, operation, and inspection of these structures. By addressing these issues head-on, advocates will be better equipped to have direct dialogue with those in the profession who remain skeptical about the hidden potential for a construction material that is strong, light, and corrosion resistant.
