TL rating for Strong-Post W-Beam Guardrail at 75" o.c.?

[BlastResistant]

Hi all,

Can any of you transportation/highway design guys/gals help me out? I need to know if there's a TL rating for a typical single w-beam metal guardrail with strongposts at 75" on center. I looked through all the AASHTO Roadside Design Guide and other references and couldn't find anything (maybe I overlooked it?).

Anyway, I'm a structural guy so I have no clue. Wondering why I need to know? Well, it's a long story, but any help would be greatly appreciated.

Thanks in advance...

You may get better responses if :
You post this on the Structural forum on this website and,

You spell out what a TL Rating is. Some of us don't know this particular alphabet soup.

good luck
