Performance Level 2 Tests on a 29-in. Open Concrete Bridge Rail
James Holloway, Ronald Faller, Daniel Wolford, Dan Dye, Dean Sicking
A safety performance evaluation of a 737-mm (29-in.) high open concrete bridge rail was conducted for the Nebraska Department of Roads (NDOR). The evaluation included four full-scale crash tests at two critical impact locations. Concerns regarding structural adequacy, snagging at the gap, single-unit truck rollover, and occupant compartment deformation of pickups were to be addressed at each critical impact location. Each impact location was evaluated with a single-unit truck and a ballasted pickup truck. The safety performance of the 737-mm (29-in.) high open concrete bridge rail was shown to meet the Performance Level 2 (PL-2) requirements specified in the American Association of State Highway and Transportation Officials (AASHTO) Guide Specifications for Bridge Railings, 1989.
