DYNAMIC TESTS OF THE CALIFORNIA TYPE 15 BRIDGE BARRIER RAIL SERIES XXV

The results of two full scale vehicle impact tests into the California Type 15 Bridge Barrier Rail are reported. The Type 15 bridge rail is a semi-rigid system consisting of two 3 1/2-in. square structural steel tubular rails mounted at 14 and 27-in. above the pavement on 6 WF 25 steel posts bolted to the edge of the concrete bridge deck. Tests were conducted at impact velocities of approximately 60 mph and approach angles of approximately 15 degrees. The test results indicated that this bridge rail design will retain and redirect a 4500 lb. passenger vehicle impacting at a 60 mph velocity and an angle of 15 degrees with tolerable deceleration rates, moderate vehicle damage; and if the barrier post spacing is 8.0 feet or less, minimal barrier damage.
