Asphalt Tonnage Calculator
Calculate the required tonnage of asphalt for your project
Results
Total Area: 0 sq ft
Total Volume: 0 cubic yards
Total Tonnage: 0 tons
Core Formula
Asphalt Tonnage (Tons) = (Volume (cubic yards) × Density (lbs/cubic yard)) ÷ 2000
Key Parameters:
- Default Density: 4050 lbs/cubic yard (standard hot mix asphalt density)
- 2000: 1 ton = 2000 pounds
Calculation Steps
1. Calculate Volume (cubic yards)
Volume = (Area (sq ft) × Thickness (inches)) ÷ 324
324: Conversion factor (12 inches/foot × 27 cubic feet/cubic yard)
2. Calculate Tonnage
Tonnage = (Volume × 4050) ÷ 2000
Example Calculation
Scenario
Paving a driveway of 20 feet × 30 feet with 4 inches thickness.
1. Volume Calculation:
(20 × 30 × 4) ÷ 324 = 2400 ÷ 324 ≈ 7.41 cubic yards
2. Tonnage Calculation:
(7.41 × 4050) ÷ 2000 = 30,010 ÷ 2000 ≈ 15 tons
Quick Reference Table (Based on 4050 lbs/cubic yard)
| Area (sq ft) | Thickness (inches) | Asphalt Tonnage (Tons) |
|---|---|---|
| 500 | 2 | ≈6.25 |
| 1000 | 3 | ≈18.75 |
| 1500 | 4 | ≈37.5 |
Important Notes
Density Adjustments
- Porous Asphalt: ≈3800 lbs/cubic yard
- Modified Asphalt: ≈4200 lbs/cubic yard
Compaction Loss
Order 5-10% extra material (volume reduces after compaction)
Unit Conversions
- 1 cubic yard = 27 cubic feet
- 1 ton (US) = 2000 pounds
