Pole barn pad depth
Plan the pad around what the barn will hold. Hay and tools sit fine on 4 inches of compacted stone; tractors, trucks or a later slab pour justify 6 to 8 inches built up in compacted lifts.

Extending the pad past the walls
Many owners run the stone 1 foot beyond each wall: 62x82 feet, 5,084 sq ft, about 141.2 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.
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.
