Strengthening of Rural Bridges Using Rapid-Installation FRP Technology

Three bridges were strengthened using an innovative method developed at University of Missouri – Rolla. It consists of strengthening reinforced concrete members using Fiber Reinforced Polymer (FRP) laminates, having high bearing and longitudinal strengths, mechanically fastened to concrete elements using wedge anchors spaced in a proper pattern. It results rapid and uses conventional typically available hand-tools, lightweight materials and unskilled labor. The three bridges are No. 1330005, No. 3855006 and No. 2210010. Bridge No. 3855006 was originally constructed in 1976 while the year built is not known for the other two bridges.
