Concrete Barrier Sloped End Section

State UT
Description Text

What are your thoughts on this design passing a TL-2 test?  My thoughts are, the vehicle will most likely rollover and crush the passenger compartment resulting in a failure.


Thank you for your time,

Crash testing under an old NCHRP study revealed that these sloped end treatments up to full PCB height will result in vehicle instabilities and rollover at speeds similar to TL-2.

The only MASH TL-2 evaluation of a similar end treatment was a shorter option for a TL-2 PCB.
