Compliance Crash Testing of the Type 60 Median Barrier

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.
