How many loads
With about 10 percent extra, this is 101.0 tons, roughly 7 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
A new driveway usually starts with a larger base stone on compacted subgrade, then a top layer that packs. Topping up an existing drive takes much less, often 2 inches. Fabric under the base helps on clay or wet ground.
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. Crusher run mixes stone and stone dust, so it packs nearly solid when compacted in layers. Round up by about 10 percent for compaction and uneven ground.
