Project 3.04: Testing, Monitoring and Analysis of FRP Girder Bridge with Concrete Deck

Testing, Monitoring and Analysis of FRP Girder Bridge with Concrete Deck

Project 3.4

Project Summary

Based on successful testing and supporting research conducted by UMaine on a new, hybrid FRP-concrete girder, a demonstration bridge using this technology in Hampden, Maine will be constructed in the 2020. This bridge has been designed in partnership with Advanced Infrastructure Technologies of Orono, Maine. Our prior experience indicates that first-time construction of a new bridge technology invariably brings to light construction challenges and highlights unanticipated design challenges. This project provides a one-time opportunity to monitor and assess performance of a novel in-service composite bridge. Data gathered from the testing, monitoring and advanced analyses proposed as part of this research will help drive acceptance of this novel FRP girder bridge system.
