Universal aggregate gradations
Universal aggregate gradations
(OP)
Hello there,
Pardon my seeming lack of knowledge. I've been doing environmental work and I've been pulled onto my first road project so I have a lot of questions.
I was wondering if there's a universal way to call out aggregate? It seems there's millions of ways it's called out. For instance, in Illinois we used CA-6 to backfill a parking lot. Now, I've got to meet section 1033.02.7 of Nebraska Specs (NDOR 2007). It's a bit confusing.
Do these vary by state? Is there a universal way to call out aggregate. I've seen people in posts say things such as "lay down some no. 87 rock", or "use no. 59 rock for bedding". Where do these numbers come from?
If anyone can shed any light on this it would be sweet.
Peace,
Stoddardvilla

M6 - Fine Aggregate for Portland Cement Concrete
M29 - Fine Aggregate for Bituminous Paving Mixtures
M43 - Sizes of Aggregate for Road and Bridge Construction
M45 - Aggregate for Masonry Mortar
M80 - Coarse Aggregate for Portland Cement Concrete.
Note that some of these also have an ASTM designation.

If you have time it's always nice to contact at least one quarry near the project location to find out what type(s) of materials they sell. Quarries usually like to sell their products for local road projects, so they usually have several products that match up with that state's transportation specs. While you're on the phone with the quarry take the time to ask for pricing. Then you have some of the info you'll need to estimate the import and hauling costs.

It's a pdf, so here it is as .txt It looks real ugly, due to columns, etc. But if you copy and paste back into Word, etc it should realign itself.
