How this is calculated
volume ft³ = area × (depth ÷ 12); tons = ft³ × 145 lb/ft³ ÷ 2000
- Compacted hot-mix asphalt weighs about 145 lb per cubic foot; mixes vary between roughly 140 and 150.
- Depth is the COMPACTED depth — loose material compacts by roughly 20%, so order accordingly.
- A residential driveway is typically 2–3 in over a prepared base; heavier loads want more.
Questions Fréquentes
How does the Asphalt Calculator work?
It applies the formula volume ft³ = area × (depth ÷ 12); tons = ft³ × 145 lb/ft³ ÷ 2000. Enter your measurements and the result updates instantly in your browser — nothing is uploaded and no sign-up is needed.
Why should I include a waste allowance?
Offcuts, spillage, breakage and an uneven sub-base all consume material that the raw geometry does not account for. The default allowance is deliberately modest; increase it for complex layouts, and remember that running short usually costs more in a second delivery than the surplus did.
Are the results exact?
They are a close estimate, not a guarantee. Compacted hot-mix asphalt weighs about 145 lb per cubic foot; mixes vary between roughly 140 and 150. Real materials vary by supplier, moisture content and compaction, so confirm the rate with your supplier before placing a large order.
Is this tool free?
Yes, completely free with no registration. All calculations happen client-side in your browser.
Does it work on mobile?
Yes. The calculator is fully responsive and works on phones and tablets in any modern browser — useful when you are measuring on site.

About the Asphalt Calculator
The Asphalt Calculator converts a paving area and compacted depth into the tonnage of hot-mix asphalt you need to order. Enter your measurements and the result updates as you type — there is nothing to submit and nothing to wait for.
Everything runs in your browser. Nothing you enter is sent to a server, there is no sign-up, and there is no usage limit.
Who it's for
Anyone paving a driveway or parking area, and estimators checking a quote.
How the calculation works
volume ft³ = area × (depth ÷ 12); tons = ft³ × 145 lb/ft³ ÷ 2000
The result depends on a few standard constants, which are stated on the page rather than hidden:
- Compacted hot-mix asphalt weighs about 145 lb per cubic foot; mixes vary between roughly 140 and 150.
- Depth is the COMPACTED depth — loose material compacts by roughly 20%, so order accordingly.
- A residential driveway is typically 2–3 in over a prepared base; heavier loads want more.
Getting an accurate estimate
Measure twice. Small errors in a linear dimension compound, because material volume scales with two or three of them at once — a 6-inch error across a 20-foot run is over a cubic foot of material on a 4-inch pour.
Keep the waste allowance. The default is deliberately conservative: offcuts, spillage, uneven sub-base and breakage are all real, and running short mid-job usually costs more in a second delivery than the surplus did.
Round up when you order. Suppliers sell in fixed increments — quarter yards, whole bags, full boxes — so treat the figure here as the minimum you need rather than the exact amount to buy.
