Design and Repair of Glass Fiber Reinforced Polymer Concrete Bridge Barriers

Steel reinforced concrete barriers, even when using epoxy coated steel reinforcement, have experienced premature deterioration due to salt exposure resulting in reduced service life. One solution is to use noncorrosive reinforcing materials such as glass fiber reinforced polymer (GFRP) in lieu of traditional steel or steel-coated reinforcement. Research and limited application by state departments of transportation (DOTs) has demonstrated the viability of GFRP as an alternative construction material for bridge barriers. Research is needed to develop nationally accepted design and repair requirements for use of GFRP in concrete bridge barriers. The research outcome should help highway agencies make more informed decisions regarding the type of bridge barriers used and selection of repair strategies. The objective of this research is to develop design requirements for (1) new GFRP reinforced concrete barriers and (2) repair of damaged barriers using GFRP. The new requirements shall be according to the American Association of State Highway Officials (AASHTO) Manual for Assessing Safety Hardware (MASH).
