27” W-beam Guardrail Testing

Question
State KS
Description Text

Do you guys know of any successful tests on 27" W-beam per TL-3?  The reason I ask the RDG makes reference to these and others are saying it has never passed at 27".  If so can you provide me some basic information, i.e. date, TL, w-beam height, testing facility, etc.?

 

The RDG will specify 27.75" minimum with emphasis to use taller w-beam.
