Extending the pad past the walls
Many owners run the stone 1 foot beyond each wall: 42x66 feet, 2,772 sq ft, about 79.6 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
If you haul it yourself, a typical half-ton pickup should carry only about half a cubic yard of stone, well under what the bed looks like it can hold. Crusher run mixes stone and stone dust, so it packs nearly solid when compacted in layers. Round up by about 10 percent for compaction and uneven ground.
