Truck loads
Plan for about 244.4 tons with waste. On a 15-ton truck that is about 17 trips; spreading while dumping (a tailgate spread) puts the stone close to where it belongs.
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. Long drives benefit from a crown so water runs to the edges.
Getting it delivered
If you haul it yourself, a typical half-ton pickup should carry only about half a cubic yard of stone, well under what the bed looks like it can hold. Road base is a graded stone-and-fines mix built to compact into a load-bearing layer. Round up by about 10 percent for compaction and uneven ground.
