How to properly install a gravel driveway
Hi, we're building a house in Oklahoma on 10 acres. We haven't yet gotten to the landscaping stage, but we do need advice on our driveway.
The driveway is approximately 600 ft long and 12 ft wide. There's no way we can afford to pave it or go with the more expensive options. I'm just wondering what we need to do to make sure the gravel/base is properly installed.
Do we need some kind of base? (other than 2" or larger gravel) So far I've been told by the gravel guys that we just need to dump about 120 tons of 2 1/2" or 3" gravel on it, spread it with a tractor, let the concrete trucks and others roll over that and then later put on a couple of truck loads of 1 1/2" gravel or crushed asphalt.
Will this last? I've been told by others that with a gravel drive, you just need to budget for continually dumping more gravel on to it as the old sinks into the earth. Is that true? Is there a way to (relatively cheaply) prepare the base so that doesn't happen?
Another fellow (who mostly does parking lot paving) suggested CKD dust to stabilize the base, but he wasn't sure what would happen to the base if it wasn't then paved eventually (thus sealing the base from water in the future).
Folks on this forum seem to have a little more expertise, so any advice would be greatly appreciated.
Thanks! -- Micah
p.s. - currently the driveway is just very sandy/muddy soil from all the trees being excavated approx a month ago.
