How many loads
With about 10 percent extra, this is 122.2 tons, roughly 9 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. Long drives benefit from a crown so water runs to the edges.
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. Road base is a graded stone-and-fines mix built to compact into a load-bearing layer. The scale ticket is the real weight; tons per yard here is a planning figure.
