Errrr,
I'm not a road expert - but from the contractors I've discussed with, the road base is usually aggregate (rock).
I don't know if sand will work. (seriously, I have no idea)
Depending on where you live, and the soil types you have - you can always contact your local city roads department. I've found the city engineers are usually very helpful and easy to talk to.
