Hello Gravel describes the difference this way: road base (crusher run) keeps its fines and packs hard, while No. 57 is clean stone that lets water move through it. Road base goes underneath as the foundation, with No. 57 or driveway gravel on top.
Working it out
Cubic yards = area × depth ÷ 324 (sq ft and inches). Tons = cubic yards × weight per cubic yard.
For 200 sq ft at 3 inches, both need 1.85 cubic yards: 2.39 tons of no. 57 stone or 2.78 tons of crusher run.
