A standard dump truck holds 10-16 tons of gravel (20,000-32,000 lbs).
Dump truck gravel capacity varies by size: small trucks (½-1 ton), standard tri-axles (10-16 tons), and heavy-duty models (up to 25 tons). Payload depends on truck bed volume (typically 10-18 cubic yards) and gravel density (~2,800 lbs per cubic yard). Always confirm with load limits to avoid overloading.
Factors Affecting Gravel Capacity
- Truck size: Single-axle (smallest), tandem-axle (mid-range), or tri-axle (largest).
- Gravel type: Dense materials (e.g., crushed stone) weigh more than lightweight options (e.g., pea gravel).
- Local regulations: Road weight limits may restrict maximum payload.
- Bed dimensions: Cubic yard capacity × gravel density = total weight.
Dump Truck Gravel Capacity Comparison
| Truck Type | Bed Volume (Cubic Yards) | Max Gravel Weight (Tons) | Typical Load (Tons) | Best For |
|---|---|---|---|---|
| Small (Single-Axle) | 5-7 | 5-8 | 3-5 | Residential projects, tight spaces |
| Standard (Tandem-Axle) | 10-12 | 12-16 | 10-14 | Driveways, landscaping, medium jobs |
| Large (Tri-Axle) | 14-18 | 20-25 | 16-20 | Commercial sites, bulk deliveries |
How to Calculate Gravel Tonnage for Your Truck
- Measure bed dimensions: Length × width × depth (in feet) ÷ 27 = cubic yards.
- Check gravel density: Most gravel weighs 1.4-1.7 tons per cubic yard (2,800-3,400 lbs).
- Multiply volume × density: Example: 12 cubic yards × 1.5 tons = 18 tons max capacity.
- Subtract truck weight: Ensure total doesn't exceed GVWR (Gross Vehicle Weight Rating).
Common Gravel Types & Their Weights
- Crushed stone: 1.6-1.8 tons/cubic yard (heaviest).
- Pea gravel: 1.3-1.5 tons/cubic yard (lightweight).
- River rock: 1.5-1.7 tons/cubic yard (varies by size).
- Decomposed granite: 1.4-1.6 tons/cubic yard.
Safety & Legal Considerations
- Overloading risks: Fines, tire blowouts, or structural damage.
- Permits: Required for loads exceeding local weight limits.
- Tarp laws: Many regions mandate covering loose gravel.
- Scale verification: Weigh loads at certified scales to avoid violations.
