I will not pave my driveway. Asphalt is only as good as the ground under it, and we get kind of swampy in the winters. Some "fine" quarry rock is best cap for any drive way, which is 1/4 minus or 3/8 minus, depending on your source. Not river rock which is round and rolls around. Do crown it a bit in the center, for water run off, and the dirt packs all the loose stuff in, or just let "nature" take its course and leaves and stuff will eventually pack every thing in place. Spread some dirt on top, like 1/2 inch or so, and it will pack as tight as concrete, and I did residential concrete for 30 years.

You are absolutely right, the ground and base is everything. In our case, when we moved here I cut a new driveway from the street through the woods, and u the hill along the side of a big sloped field - everything well drained. No soft or swampy areas.
It was tractor and yard box, cut and fill, cut and fill, reshape the ground, compacted it well, then spread 300 tons of grave. Packed that down with a wheeled skid steer with a heavy load of gravel in the bucket. The base is SOLID! For 20 years we drove over it, regraded, and added more gravel if needed. I used only crushed granite from the local rock quarries.
For one section I paid for commercial grade asphalt (more and bigger rock, different asphalt blend, much thicker layer) where I may need heavy equipment and loaded trucks, put residential grade around the circular drive by the house and from the county road down into the woods. I have a completely separate gated entrance I use for heavy trucks and equipment.
This area is mostly eroded mountains, big rock not far underground everywhere.
When I dig a hole on my property, or grade a section I always run into rock. Some have been huge and took all my wits to dig up and move.
This one was sticking a few inches out of the ground where I was grading. After digging deep all the way around I got worried. Then when trying to pry it out of the ground with the skid steer the top half separated from the bottom along a thin mud line and I could roll the top out and fill the hole in. Anyone need a nice dome-shaped decorative rock for their yard? You can move it.
My son got in the photo for scale.
I pulled this one out while digging a piy-burning hole. A young friend got a lesson operating the skid-steer and moved it for me!
What is frustrating is to start digging out big stump I find the roots had grown around or down through cracks in big rocks. That's the only time I wished I had access to some REALLY big equipment.
