Extending the pad past the walls
Many owners run the stone 1 foot beyond each wall: 62x102 feet, 6,324 sq ft, about 175.7 tons at 6 inches. It keeps mud away from the doors and protects the post bases.
Layering the base
Strip topsoil, level and compact the subgrade, then spread stone in lifts of about 3 to 4 inches, compacting each. A coarser base topped with a finer, packable stone often makes the most solid floor.
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. 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.
