If I eventually plan to install an asphalt driveway, what is the best size and type of stone to apply in the interim?
The best initial base for an asphalt driveway that is to be graded and paved consists of an initial layer of #2 stone followed by a layer(s) of #57. To ensure a solid base, these should be in place as long as possible so that the repeated movement of vehicles over the surface drives the stone into the ground.
