Minimum rcp cover
Minimum rcp cover
(OP)
Hi,
Due to r.ow. limitations, we cannot raise the pgl for a highway project under design. However, I read somewhere that you need to have a minimum cover on rcp culverts for arroyo crossings in the project. Does anybody have any idea what's that minimum cover? We're proposing class iv.
Thank you,
Roberto.

RE: Minimum rcp cover
of your conditions I may be able to give you the min cover.
Don't rule out Class V if things get real tight. Good Luck.
RE: Minimum rcp cover
Thanks for the reply. We have a couple of rcp circular culverts, one 24" and one 36" located in different arroyos crossing this rural highway. Both culverts only have 2.5" hmac and 8" crush stone base over them, that is 1.05' cover. The pipes are laid out on regular ground and the fill is surrounding and over the pipe. I would like to know if this is sufficient for the class iv pipes to support the hs-20 loading over them and if we should change the class.
I really appreciate your help, thank you.
Roberto

I am sorry. It's 2.5" hmac and 10" stone crush base course.
