Abstract:

Three bridge rail systems were evaluated by crash test as installed on a curved, superelevated downgrade alignment. Concrete safety shape barriers mounted vertical and perpendicular to the superelevation, and a tubular three beam system were evaluated. Test vehicles included an. 1800-lb (820-kg) class mini-compact car, a 2250-lb (1020-kg) class subcompact car, and a 20,000-lb (9070-kg) school bus. Impact conditions for all tests were 40 mph (64 km/h) and a 15-deg angle (as measured at the curve tangent). Findings indicate successful performance of all three barrier systems for the full range of vehicles. other tasks in the program included measurement of vehicle mass properties and geometries of a 40,000-lb (18,140-kg) intercity bus, two 20,000-lb (90i0-kg) school buses, and a 2250-lb (1020-kg) subcompact car. In addition, front corner vehicle crush properties were measured for a school bus and a subcompact car. This volume describes in detail the findings of the project; a summary of the work is provided in the Executive Summary, Volume 1.
