Layers for a lasting driveway
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.
Buying the stone
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. #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.
