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: 26x32 feet, 832 sq ft, about 21.6 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.
Getting it delivered
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. Crushed stone has angular faces that lock together under a compactor, which is why it holds a pad shape. Round up by about 10 percent for compaction and uneven ground.
