Dynamic tests of the California type 15 bridge barrier rail. Paper presented at the 51st Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1972.

This paper presents the results of full-scale vehicle impact tests on a bridge barrier rail consisting of square tubular steel rails mounted 14 inch and 27 inch above the pavement on steel posts bolted to the edge of a concrete deck. It was concluded that this design with post spacings at 8 ft will satisfactorily retain and redirect a 4500 lbs impacting vehicle at speed of 60 mph and an angle of 15 degrees.
