Long-term Behavior of GFRP Reinforced Panels after Eight Years of Field Exposure

Since 1998, Missouri Science & Technology (S&T)/University of Missouri-Rolla investigators have been involved in more than 25 bridge repairs and/or new bridge construction involving composite materials. To date, many of these projects have shown reliable field performance. However, there have been little follow-up investigations to study their residual capacity and behavior after long-term exposure to conditioning. This study will examine the crack pattern development over time in glass fiber reinforced plastics (GFRP) reinforced panels fabricated in 2005 and exposed to field conditions. The study will also test and autopsy the GFRP reinforcing bars to examine property degradation. The GFRP reinforced panels will be studied in flexure to examine any degradation in flexural behavior.
