Depending on what the subsoil is, it may be necessary to compact the
subsoil so that the gravel doesn't sink into it. Worst case requires
importing a suitable subsoil base before the gravel. I'd also
investigate what people build gravel driveways out of in your area.
If there's a suitable local material, it'll be cheaper than limestone.
Unless, of course, limestone is the suitable local material...
Trucking rocks isn't cheap.
