Guardrail loading - AASHTO 1957 Specs or older 1

[Mafradu]

Hello,

Would someone have an excerpt of the guardrail loading specified in the AASHTO 1957 specs or older version? I have looked everywhere and cannot find anything. Any help would be appreciated.

Thanks

I don't the 57 AASHTO but I have the 57 AASHO . The 53 spec is the same as 57.

Bridgebuster, you are a lifesaver. Thanks!

you're very welcome Mafradu. I have all of the AASHTO specs from '53 on. I had the ones from the 40's but they grew legs. If you need any excerpts let me know.
