Comment utiliser ce calculateur
- Choose a material, or enter a custom density from your supplier.
- Enter the length, width and depth of the area. Driveways typically need 4–6 in (10–15 cm) of compacted aggregate.
- Add a small allowance for compaction and uneven ground.
Formule
Suppliers sell aggregate by weight, so volume is converted with the material's bulk density.
Volume = L × W × D × (1 + allowance)
Weight = volume × density
1 US ton = 2,000 lb = 907.18 kg; gravel ≈ 1.4 tons per cubic yard
Example
- 30 × 10 ft path, 4 in deep: 100 ft³ = 3.70 yd³ (2.83 m³).
- +5% = 2.97 m³ × 1,680 kg/m³ ≈ 4.99 t ≈ 5.5 US tons.
Questions fréquentes
How much does a cubic yard of gravel weigh?
Typically 2,500–3,000 lb (about 1.25–1.5 US tons), depending on stone type, size and moisture.
Should I account for compaction?
Yes. Crushed stone compacts by 10–15%; increase the allowance if you'll compact with a plate compactor.
What depth do I need for a driveway?
Often a 4–8 in (10–20 cm) compacted base of larger stone plus a 2–3 in top layer, depending on soil and traffic.
