EVALUATION OF BREAKAWAY CABLE TERMINALS FOR GUARDRAILS

SERVICE REQUIREMENTS FOR GUARDRAIL TERMINALS SHOULD PLACE EMPHASIS FIRST ON SAFETY, SECOND ON ECONOMICS, AND THIRD ON AESTHETICS. SUCH TERMINALS SHOULD (1) DEVELOP TENSILE AND/OR FLEXURAL STRENGTH NECESSARY TO ENSURE DESIRABLE REDIRECTION PERFORMANCE OF THE LENGTH-OF-NEED SECTION; (2) EITHER BY REDIRECTION, CONTAINMENT, OR CONTROLLED PENETRATION, MINIMIZE VEHICLE/OCCUPANT DECELERATIONS FOR TERMINAL SECTION IMPACTS. THIS IMPLIES THAT IMPACTING VEHICLE IS NOT LAUNCHED, ROLLED, OR POCKETED. (IN SOME CASES END-ON IMPACTS CAN BE ELIMINATED; E.G., EXTENDING THE RAIL END INTO THE BACK SLOPE.); (3) MINIMIZE THE POSSIBILITY OF PENETRATION OF THE VEHICLE PASSENGER COMPARTMENT BY A SYSTEM COMPONENT; (4) BE ECONOMICAL IN CONSTRUCTION, DAMAGE REPAIR, AND MAINTENANCE; (5) MINIMIZE VEHICLE DAMAGE; AND (6) HAVE A PLEASING AND FUNCTIONAL APPEARANCE. THIS DIGEST IS INTENDED TO MAKE AVAILABLE, FOR EARLY IMPLEMENTATION, THE DETAILS OF A TERMINAL CONCEPT THAT HAS MET THESE SERVICE REQUIREMENTS IN CRASH TESTS CONDUCTED IN NCHRP PROJECTS 15-1(2) AND 22-2. /NCHRP/
