I have section of(dirt& gravel and fill material) drive way that is up against a retaining wall (I want to improve). The area has been filled with crushed rock (concrete fill) with a layer of sand over the rock. I've removed some sand and tamped the sand flat.
I'm wondering whether I should lay crushed rock and stone dust and tamp again, and another layer of sand and screte before laying brick? Versus laying the brick down, concreting an edge and laying sand on top to hold the brick joint(s).
I am planing on a concrete edge on the brick driveway.
There isn't any house foundation to interfere.

A driveway needs a very strong solid base to be able to support a vehicle.
It really needs the stone base locked together tight and that usually takes a mechanical tamping.
If you get it tightly locked than lay brick, then you just need to build the concrete edging, then sweep a sand mixture into the joints and run a mechanical tamper one more time , but use a piece of old carpeting under the plate to keep it from breaking the brick, or scratching I also.
