Role Of Grout And GFRP Slip Liner On The Circumferential Behaviour Of Retrofitted Corroded Metal Culverts

For any aging infrastructure, its probability of failure increases with time. There are a multitude of ways to repair and rehabilitate deteriorating pipes, and as the infrastructure system continues to age, it is important to understand and promote the use of effective and durable materials for retrofit. Fiber reinforced polymer (FRP) composites have shown to offer an attractive alternative to replace the deteriorating steel in structural corrugated metal pipes (CMPs). FRP composites have significantly improved durability characteristics compared to steel, which will reduce maintenance costs and improve lifecycle costs. Other materials such as HDPE slip liners for retrofit are in existence but their durability and improvement to load carrying capacities is under question. Past experimental work has shown GFRP to be a suitable material for developing composite action with corroded steel using a polymer grout. Longitudinal testing of corroded CMP with glass fiber reinforced polymer (GFRP) slip liners has garnered interest of the New Mexico DOT. However, field conditions are more circumferential dominant behaviors, and no data exist on this performance measure for CMPs with GFRP slip liners. The proposed work will help evaluate the parameters obtained from circumferential bending necessary to develop design for field implementation using GFRP slip liners with different grouts for corroded culvert retrofit.
