📋 How to Calculate Asphalt Tonnage
- Area (sq ft) = Length × Width
- Volume (cu ft) = Area × (Thickness ÷ 12)
- Cubic Yards = Volume ÷ 27
- Tons Required = Cubic Yards × 2.0
Standard asphalt density: 145 lbs/cu ft or 2.0 tons/cu yd.
❓ Asphalt Calculator FAQ
How do you calculate asphalt tonnage?
Multiply Length × Width to get area. Multiply by thickness (in feet) for volume. Divide by 27 for cubic yards. Multiply by 2.0 for tons. Formula: Tons = (L × W × T/12) ÷ 27 × 2.0
How many tons of asphalt for a standard driveway?
For a 20’×40′ driveway at 2 inches thick, you need approximately 9.88 tons. Coverage is about 80-100 sq ft per ton at 2 inches thickness.
