Preservation of Missouri Transportation Infrastructure - Validation of FRP Composite Technology Through Field Testing

Under the work of a research team at the University of Missouri-Rolla (UMR), this project is intended to validate the use of fiber-reinforced polymer (FRP) materials as a means to strengthen existing concrete bridges that are considered structurally deficient. Five existing concrete bridges, geographically spread over three Missouri Department of Transportation (MoDOT) districts, were strengthened using five different composite technologies that go under the names of manual lay-up FRP laminates; adhered pre-cured FRP laminates; near surface mounted (NSM) FRP bars; mechanically fastened FRP laminates; and, steel reinforced polymer (SRP). The aim of the present project is to make these strengthening technologies available to bridge owners and professionals through the development of proposed FRP bridge strengthening design, materials, and construction specifications for potential American Association of State Highway and Transportation Officials (AASHTO) adoption. Validation of composites, taking into account durability issues and cost impact, is undertaken with a five-year monitoring program with an emphasis on non-destructive testing (NDT) evaluation.
