In many ways it depends on the type of dirt and the traffic you expect. In Oregon, for my driveway the county required 6-8" of pit run shale with 2-3" of 3/4 minus crushed rock on top of it. They preferred it compacted with a vibrator , but you were allowed to compact it by running a fully loaded dump truck over it. So, in that case we roughed it in with a dozer and finished it off with a dump truck. Possibly not the implements you were thinking of.
If you have different soil, or very light usage you could get someone with a dozer to rough it in, or do it yourself with a box blade, if you have a big enough tractor and lots of time.
