How to use this calculator

  • Enter the paved area and thickness.
  • Use density 145 lb/ft³ for standard hot-mix; adjust if your supplier specifies a different density.
  • Check the breakdown for total weight if your supplier prices in tons or short tons.

About this calculator

Asphalt is sold by the ton, and 1 cubic foot of compacted hot-mix weighs about 145 lb. A residential driveway typically uses 2-3 inches of asphalt over a properly prepared 4-6 inch gravel base. Always order at least 5% extra to cover edge spread and roller compaction.

Frequently asked

How thick should my driveway asphalt be?+
2 inches for an overlay on existing pavement. 3 inches for a new driveway over a gravel base. 4+ inches for parking lots and high-traffic surfaces.
Cold patch vs hot mix?+
Hot mix is the permanent answer. Cold patch is for emergency pothole repair — it does not bond as well and breaks down faster.
Does the temperature matter?+
Yes — hot mix needs to be laid at over 250°F and rolled before it cools below ~175°F. Schedule paving on warm, dry days.
What is the gravel base for?+
A 4-6 inch compacted gravel base provides drainage and prevents the asphalt from cracking when the sub-grade flexes.
How much does asphalt cost per ton?+
In the US, hot-mix asphalt is roughly $100-150 per ton at the plant in 2026, plus delivery and laydown labor. Spot-check local quotes.
