Truck loads
With about 10 percent extra, this is 21.2 tons, roughly 2 loads if the yard runs 15-ton trucks. Ask the driver to tailgate-spread it along the drive to save hours of raking.
Base and top layer
If this is a new driveway on soil, build a base of 4 to 6 inches of coarse stone first and finish with a packable surface stone. For a refresh, 2 inches over the old surface is common. Add culverts or ditches where water crosses the drive.
Getting it delivered
Most quarries and landscape yards deliver by the ton; ask whether there is a minimum and a delivery fee, and where the driver can dump without damaging your lawn. Asphalt millings bind into a fairly firm surface when compacted and warmed by the sun. Round up by about 10 percent for compaction and uneven ground.
