Abstract
Five full-scale dynamic impact tests were made on two basic geometric designs and one trial design of bridge barrier rails. This report describes the test procedures, instrumentation and test results based on the data obtained from high-speed oblique-angle impacts. Results indicated that all of the bridge barrier rails could effectively withstand the impact of a 4,300-lb car at speeds in excess of 75 miles per hour. Specific recommendations are made for a balanced design bridge barrier rail system.
