About #57 stone
#57 stone is a clean crushed stone in roughly the 1/2 to 1 inch range with very few fines. It drains fast, which suits drainage layers and the top of a gravel drive, but it does not pack into a hard crust by itself. Typical weight: 1.3 to 1.45 tons per cubic yard.
Ordering checklist
- Measure odd shapes in pieces. Split curves and L-shapes into rectangles and add them.
- Add a margin. About 10 percent covers compaction and low spots.
- Bulk or bags. Bulk delivery is the practical choice here.
- Prep first. Remove sod, compact the subgrade and set edging before the stone arrives.
Use the volume and tonnage calculator for any other size.
When to choose #57 stone
Works well for:
- French drains and drainage layers
- The top course of a gravel driveway
- Under sheds where water needs to drain away
Poor fit for:
- A standalone base, since it does not pack hard without fines
- Paver setting beds
- Walk paths meant for strollers or wheelchairs
Quick reference numbers
- Per inch over 100 sq ft: about 0.42 tons of #57 stone (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.2 tons.
- Another size for comparison: a 10x20 area at 3 inches takes about 2.5 tons.
- Weight used here: about 1.35 tons per cubic yard.
Where estimates go wrong
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
