How many loads
With about 10 percent extra, this is 84.7 tons, roughly 6 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. Fabric under the base helps on clay or wet ground.
Ordering and delivery
Small dump trucks commonly carry around 5 to 10 tons and tri-axles more, but loads vary by truck and state, so ask the yard what fits in one trip. Recycled concrete aggregate compacts well and is often cheaper than quarry stone; ask for a screened product. The scale ticket is the real weight; tons per yard here is a planning figure.
