At this depth, build in compacted layers of no more than 4 inches each. A plate compactor cannot densify a deeper lift, and uncompacted stone will rut.
Two questions in one tool. Pick an application and it tells you the correct depth and the quantity to order. Or enter the amount of stone you already have and it tells you how deep you can spread it across your area.
Two inches for decorative beds, two to three for paths, four to six for patio and shed bases, and eight to twelve for a new driveway built in layers.
Yes. More than about three inches of loose stone on a walking surface is unpleasant to walk on and unstable underfoot. Depth belongs in the compacted base, not the surface course.
No more than four inches per lift, and two inches is better. A plate compactor simply cannot densify a deeper layer all the way through.
