How many loads

Plan for about 110.0 tons with waste. On a 15-ton truck that is about 8 trips; spreading while dumping (a tailgate spread) puts the stone close to where it belongs.

Layers for a lasting driveway

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.

Ordering and delivery

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. #57 is a washed stone of roughly 1/2 to 1 inch with few fines; it drains fast but stays a little loose on its own. Round up by about 10 percent for compaction and uneven ground.
