This report documents findings of the investigation of five different brands of panel edge drains installed in a test section along Interstate 81 in Roanoke, Virginia, from Milepost 154.148 to Milepost 156.11. Findings from this study indicated that closed core edge drains (Multi-Flow, Advanedge) are less likely to become damaged or distressed than the more open core drains (Contech, Akwadrain, Hydraway). Typical distress found in the more open cores was rolling over of the top row of support columns, fabric intrusion between support columns, and rolling up of the bottom row of support columns.
