DOT batch & tech cards

i'm only guessing the DOT batch card is for approved concrete for highway construction like bridge supports, etc.???

DOT tech cards...??

i dunno, maybe as proof one can make repairs or knows the correct mix for DOT concrete..???

 

Dont know if you googled either. But it came up with interesting results.
Looks like both might be state issued things.


Be nice if someone on here has the correct answer, you have me curious now.

 

this is what i found....(from Florida)
