Need help identifying gravel number.

Hello,

My driveway is needing a new load of gravel but I don't remember exactly what I bought the last time. Someone told me they are pea gravel but I sure thought pea gravel was more rounded and smooth than what I currently have. I'd appreciate it if someone could take a quick look at the attached picture and help me identify them so I can call around and check on pricing. I put a dime and penny in the picture to give some sort of reference. Sorry if this is the wrong forum by the way.

Thank's again for any help.

We would call that 3/4 minus crushed limestone.

Hey thank's for the reply. Sorry I don't know much when it comes to this exact area. Am I correct in thinking minus means it includes from 3/4 all the way down to very fine particles? I looked up what you said and it does look like it except mine has no fine stuff, just mainly what you see there. So, I'm thinking I would just call and ask for 3/4 crushed?!

Thank's again

The minus is what locks it all together... without the minus you will have more voids and shifting... 3/4 minus is your standard driveway gravel. 3/4 clean crushed limestone can also be used, it's just not as smooth.

The question is whether or not that stone originally came with other smaller sizes. Stone like that is available clean which means just those size stones and might be a #8. If it originally had smaller stones and dust then it could be #67.

A good stone for driveways is crusher run or #411. It's a blend of various sized stones all the way down to dust. It compacts very well and is often used as the base under roads. The last thing you want for a driveway is a uniform sized stone. Like XSleeper mentioned. It's the variety of sizes that allows the stones to lock (compact) together.
