How to Calculate Asphalt Tonnage (Asphalt Weight Calculator Guide)
The asphalt tons calculator uses the following standard formula:
Tons = (Length × Width × Thickness ÷ 324) × Density
Default asphalt density: 145 lb/ft³ (or 2,322 kg/m³).
You can adjust the density field based on your specific asphalt mix.
How to Use the Asphalt Mix Weight Calculator
Enter the Length and Width of your driveway or road area.
Enter the Thickness of asphalt in inches or centimeters.
Adjust the Density (if you use a different asphalt mix).
Click Calculate to get instant results.
You’ll see results for:
Asphalt Volume (ft³, yd³, m³)
Asphalt Weight (tons and kilograms)
Truckload Estimates (20 tons per truck)
Optional 5% material wastage
This asphalt paving material estimator helps ensure you order the correct amount of mix without overspending.
Understanding Asphalt Weight and Volume
The asphalt mix weight calculator automatically converts asphalt volume to tons using your entered dimensions and density.
For example:
1 cubic yard of hot mix asphalt weighs about 2,025 kg (2 tons).
1 ton of asphalt typically covers 35–40 sq ft at 1.5 inches thick.
Accurate tonnage estimates reduce material waste, delivery delays, and project costs.
Why Accurate Asphalt Tonnage Matters
Estimating hot mix asphalt tonnage correctly helps you:
Avoid material shortages during paving.
Plan truck deliveries efficiently.
Manage costs and prevent over-ordering.
Ensure proper paving thickness and compaction.
With our asphalt weight calculator, you’ll always know exactly how much mix to order before your project begins.
Pro Tips for Accurate Results
Always measure your project area twice before entering dimensions.
Round thickness to the nearest half inch for precision.
Add a 5% buffer for uneven surfaces or wastage.
Verify mix density with your supplier — not all hot mix asphalt has the same weight per cubic foot.

Frequently Asked Questions
1. How do you calculate asphalt tonnage?
You multiply project area (length × width × thickness) by asphalt density, then divide by 2,000 to get tons. Our asphalt tons calculator does this automatically.
2. What is the density of asphalt per cubic foot?
Standard hot mix asphalt has a density of 145 lb/ft³ or about 2.32 g/cm³.
3. How many tons of asphalt fit in one truckload?
A typical dump truck can carry 18–20 tons of asphalt per load.
4. Can I convert asphalt volume to tons using this tool?
Yes — the asphalt mix weight calculator converts cubic feet, yards, or meters into tons instantly.
5. Is this calculator suitable for both roads and driveways?
Absolutely! Whether you’re resurfacing a parking lot or laying a new driveway, the asphalt paving material estimator works for any surface area.
