| Abstract | Currently recommended guardrail and median barrier breakaway cable terminals (BCT) were to be evaluated for performance with 1800-lb (800-kg) class minicars. Early findings indicated unsatisfactory performance of the guardrail BCT for end-on impacts at 60 mph (97 km/h). The study was redirected to develop and evaluate a retrofit design for achieving satisfactory performance with the minicar. Subsequent to the baseline crash tests, a series of analytical studies, laboratory tests, bogie tests, and full-scale crash tests were conducted to upgrade the recommended BCT. Findings include a satisfactory end-on test, but subsequent strength test produced a vehicle penetration. Thus, a recommended upgrade design is given except that further strengthening of the beam is necessary for angular impacts downstream of the end. |
