EVALUATION OF DESIGN ANALYSIS PROCEDURES AND ACCEPTANCE CRITERIA FOR ROADSIDE HARDWARE. VOLUME II. THE EFFECT OF SOIL STRENGTH ON LONGITUDINAL BARRIER PERFORMANCE. FINAL REPORT

This research was conducted to identify and investigate aspects of NCHRP Report 230 which require additional technical research. This report deals with five broad areas of concern: (1) the importance and effect of soil conditions on the dynamic performance of barriers, (2) methods for re-evaluating pre-Report 230 test results in light of the current Report 230 criteria, (3) linking the occupant risk factor to "real-world" accident cases, (4) assessing the potential hazards of the redirected vehicle, and (5) replacement of the 4500-lb test car.
