Subject: Gravel/Dirt driveways
Most of the driveways here in NC are gravel. My observations:
remove topsoil, spread stones, drive on it
You'll want to get crushed stone (not smooth stones) that also contains the
stone dust & small grit. The stone dust/grit is what packs down into a firm
surface. A common name here is 1/2" or 3/4" Crusher Run. Smooth stones will
never lock together.
I have one section where they delivered washed stone (no stone dust). It
has never firmed up.
I'd guess that 4-6" deep is good for driveways. When you mention truck &
trailer I assume you mean pick-up truck, not 18-wheeler...
