Good post. The only thing I disagree with is disturbing the soil surface. Unless there's objects which will puncture the fabric he's better off laying it on the undisturbed soil, then graveling over the top. Elevating the road surface lets the water run off, rather than soaking in and turning the gravel to mud.I would use fabric with gravel on top. I think it's called geotextile road fabric. I would remove the topsoil down maybe 6" and then put the fabric down and fill with gravel to the same height as the surrounding soil.
