Culvert Question

[dave1949]

When this numbering process was being created how did they come up with those numbers?? My pea size (3/8" chips) brain can't find any connection.

It's all designed to obfuscate things for job security.

We use inch measurements here for most stuff. 1" minus for example is 1" stones down to dust. Bank-run is whatever is coming out of the bank at the gravel pit at the moment, so you have to ask how gnarly is it? :laughing:

On a forum like this where we all know that orange tractors are best, but then comes the problems of which shade of orange?

You reawelise of course! This means WAR!!!:shocked:

Hey, I'm out of this color war. I got orange, blue, green. Hey, I just realized I need to buy another tractor in the red color. I'll talk to the Business Manager (wife) about that.....

Wow - this thread has really come quite a long way! I appreciate everyones help. I really have a much better idea of where to go next.

In Ohio the straight gravel is roughly based on standard sieve size.
The bank run material is based on section of state specifications
304 is bank run embankment
411 is crusher run pavement

From what little I know about the "source" of the numbering, it comes down to what will pass through a certain sized screen and if it's been filtered of fines. The larger the number, the smaller the stone.

The common stones around here are:

#3 - good for base - this is a coarse stone with no fines

#57 - good for drainage, septic, etc - sizes 5 through 7, no fines

#78 - good as a sublayer under slabs, as it self compacts -- sizes 7 through 8, no fines

#8 - very similar to #78 but all uniform size 8, no fines. I used this to fill in around stepping stones in our front walkway.

21A - crusher run, everything 1/2" and smaller, including fines. This is the only one where the numbers don't make sense to me.

Here's a page from my local supplier (they are just 4 miles away, which is awesome -- I'm on a first name basis with the gal who takes orders):

Hello everyone-

This thread has really come a long way. Just wanted to post some updated pictures. We went ahead with the three pieces of concrete culvert. Its a total of 24' wide x 36". Total cost for all three was $325 with transportation.

Im so glad to those who strongly recommended that I go with the 24' vs the original plan of 16'. There is no way that 16' would have been wide enough.

We still have work to do yet, but I can get the truck across pretty easily, which is a good start....

Looks real good. You got a killer deal on them.

LD1,

Thanks - we were pretty happy with the end result. Ive been looking online to see what these concrete culverts normally cost, but I can't find anything. Anyone know? The only reason I ask is because I'm thinking of getting the the guy who sold them to me a gift card or maybe a little extra cash. I think he sold them to us for really cheap because he found out that my wife and I are military...
