How Much Does 1 Cubic Yard of Crushed Stone Weigh?

One cubic yard of clean, crushed limestone or granite weighs approximately 2,700 pounds, which converts directly to 1.35 US short tons (or 1.22 metric tonnes). This is based on a standard loose bulk density of 100 lbs per cubic foot ($2,700\text{ lbs/yd}^3$).

Crushed Stone Weight Benchmarks:

  • Clean Angular Crushed Stone (#57, #67): ~2,500 to 2,700 lbs/yd³ (1.25 to 1.35 tons/yd³)
  • Dense-Graded Base / Crusher Run (with stone dust): ~2,800 to 3,000 lbs/yd³ (1.40 to 1.50 tons/yd³)
  • Compacted Sub-Base in Place: Up to 3,100 lbs/yd³ (1.55 tons/yd³) after vibratory plate roller passes

When ordering crushed stone by the ton, remember that 1 US Ton covers approximately 0.74 cubic yards of volume (20 cubic feet).

Common Applications for Crushed Stone

Because crushed stone is mechanically fractured into jagged, multi-faceted angular pieces, its edges bite and lock together under load. This structural friction prevents rutting and lateral spreading:

Project Application Recommended Aggregate Size Recommended Depth
Driveway Base Layer Crusher Run or #3 Stone (2"–3") 4 to 6 inches (compacted)
Driveway Surface Topping #57 Stone or #8 Stone (1/2"–1") 2 to 3 inches
Patio & Walkway Paver Base Dense-Graded Base (DGA) + Stone Dust 4 inches
Concrete Slab Sub-Base #57 Washed Crushed Stone 4 inches
Retaining Wall Backfill Clean Washed #57 Crushed Stone 12+ inches behind wall

Crushed Stone Recommended Depth & Coverage Formula

When calculating crushed stone for load-bearing projects, always factor in compaction settling. Mechanical vibratory plate compactors compress loose aggregate by 15% to 20%. To achieve a true 4-inch finished depth, you must spread approximately 4.75 inches of loose material.

Depth (Finished) Sq Ft per Cubic Yard Sq Ft per US Ton (100 lb/ft³) Tons Needed for 500 Sq Ft
2 inches (50 mm) 162 sq ft ~120 sq ft ~4.2 tons
3 inches (75 mm) 108 sq ft ~80 sq ft ~6.3 tons
4 inches (100 mm) 81 sq ft ~60 sq ft ~8.3 tons
6 inches (150 mm) 54 sq ft ~40 sq ft ~12.5 tons
