Overview

Crushed stone is a versatile construction material used as a base for driveways, a drainage medium, or as an aggregate in concrete. Calculating how much you need in weight is crucial because suppliers and delivery trucks typically charge based on weight.

Pro Tips

For a stable driveway base, 4 to 6 inches of stone is industry standard.
Always order 10% extra to account for compaction; the volume decreases as the stone is rolled or tamped.
Large quantities are best delivered by dump trucks, which carry between 15 and 22 tons.

Fun Facts

"Crushed stone is made by mining rock deposits and breaking them into specific sizes."
"Most crushed stone naturally rests at an angle of 35 to 45 degrees, known as the angle of repose."
"Standard crushed stone weighs approximately 1.35 tons per cubic yard."

Formula: Tons = [Volume (ft³) / 27] × Density (lb/yd³) / 2000
