Crushed Stone vs Stone Dust
Side-by-side comparison of Crushed Stone and Stone Dust to help you choose the right gravel for your project.
Overview
Angular, mechanically crushed rock available in various sizes. Excellent for compaction and stability. Crushed stone is the workhorse of the aggregate industry, used in everything from road construction to residential driveways.
Stone dust is a finely crushed aggregate made up of stone particles smaller than 1/4 inch. It compacts tightly when installed and lightly moistened, creating a firm, smooth surface ideal for leveling and base preparation.
