DYNAMIC TESTS OF CALIFORNIA TYPE 9 BRIDGE BARRIER RAIL AND TYPE 8 BRIDGE APPROACH GUARDRAIL
THE RESULTS ARE REPORTED OF ONE FULL-SCALE VEHICLE IMPACT TEST INTO THE CALIFORNIA TYPE 9 BRIDGE BARRIER RAIL AND THREE TESTS INTO VARIOUS MODIFICATIONS OF THE CALIFORNIA TYPE 8 BRIDGE APPROACH GUARDRAIL. THE RESULTS INDICATE THAT THE TYPE 9 BRIDGE BARRIER RAIL AND THE FINAL TYPE 8 BRIDGE APPROACH GUARDRAIL DESIGNS WILL RETAIN AND REDIRECT A 4500 LB PASSENGER VEHICLE, IMPACTING AT 60 MPH AND 25 DEG, WITH TOLERABLE DECELERATION RATES, MODERATE VEHICLE DAMAGE, AND MINIMAL BARRIER DAMAGE. THE BRIDGE BARRIER RAIL AND BRIDGE APPROACH GUARDRAIL, TOGETHER, PROVIDE STRUCTURAL CONTINUITY AND A PLEASING APPEARANCE. /AUTHOR/
