Reduced-Height Performance Level 2 Bridge Rail

The safety performance of a 737-mm (29-in.)-high open concrete bridge railing was evaluated. The evaluation included four full-scale crash tests, investigating two critical impact locations where structural failure was most likely to occur. Each impact location was evaluated with a single-unit truck and a ballasted pickup truck. The safety performance of the 737-mm-high open concrete bridge rail was shown to meet the Performance Level 2 requirements specified in the AASHTO Guide Specifications for Bridge Railings (1989).
