Extending the pad past the walls
Many owners run the stone 1 foot beyond each wall: 62x82 feet, 5,084 sq ft, about 127.1 tons at 6 inches. It keeps mud away from the doors and protects the post bases.
Build it in layers
Remove sod and organic soil first. Compact the subgrade, then place and compact the stone in thin lifts. If the barn floor will be stone permanently, finish with a material that has fines so it packs firm.
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. #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. The scale ticket is the real weight; tons per yard here is a planning figure.
