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:

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.

Frequently Asked Questions About Crushed Stone
Crusher Run (also known as Quarry Process, QP, Dense Grade Aggregate, or ABC stone) is a mix of angular crushed stone (from 3/4" down to fine stone dust). The stone dust fills the air voids between larger stones, allowing it to pack down almost as hard as asphalt or concrete when moistened and rolled.
A standard commercial tri-axle dump truck typically hauls 14 to 18 tons of crushed stone (approximately 10 to 13 cubic yards), depending on local highway weight limit regulations.
