How it Works
The calculation uses the volume of the area and the density of asphalt.
Standard Formula: Volume (Length × Width × Depth) × Density.
Typical density is 145 lbs per cubic foot (approx 2.32 tons/m³). The tool converts the volume into tons directly.
What is Asphalt Calculator: Hot Mix Tonnage?
The Asphalt Calculator estimates the total weight of hot mix asphalt required for paving projects. Asphalt is sold by the ton, and accurate estimation prevents ordering too little (cold joints) or too much (wasted money).
Step-by-Step Guide
- Measure Area – Length x Width of the driveway/lot.
- Determine Depth – Input compacted thickness (e.g., 2-3 inches).
- Calculate – The tool computes the tonnage required.
- Round Up – Add 5-10% for waste and edge variations.
Example
Input: 1000 sq ft, 3 inches
Result: 18.5 Tons
FAQ
What is the standard density?
145 lbs per cubic foot is the industry standard for estimation.
How thick should a driveway be?
2 inches (compacted) for resurfacing, 3-4 inches for new driveways.
How much is a ton?
A ton of asphalt covers approx 80 sq ft at 2 inches thick.
Compacted vs Loose?
Asphalt compresses ~20%. To get 2" compacted, lay ~2.5" loose.
Base material?
You also need a solid gravel base (4-8 inches) before paving.
👷 Builder's Tip: Measure twice, cut once. These calculations are theoretical; actual site conditions may affect requirements.
Conclusion
Asphalt compacts significantly. A 3-inch loose layer might compact down to 2.4 inches. Always plan for the *compacted* thickness you want, but order enough loose material to achieve it. Consult your supplier for specific mix densities.
