Compliance Crash Testing of the Type 60 Median BarrierAuthor/Presenter: Whitesel, David; Jewell, John; Melin, Robert
The California Department of Transportation has used Type 60 Median Barrier since it passed the National Cooperative Highway Research Program (NCHRP) Report 350 safety guidelines and became a Standard Plan in 1997. It is a single-slope concrete barrier that is 36 inches high with a face sloped 9.1 degrees from vertical.
The Manual for Assessing Safety Hardware (MASH09) TL-3 pickup test (Test 3-11) had been conducted successfully on the Texas single slope concrete barrier with a barrier face slope of 10.8 degrees, which is considered to perform similarly to the Type 60 with a barrier face slope of 9.1 degrees. However, no other single slope concrete barrier has been tested to MASH TL-3 with the small car (Test 3-10).
One crash test, MASH 3-10, was conducted on the Type 60 Median Barrier. The results were within the limits of MASH guidelines.
