Estimated cost — your price

This site holds no price list for this material — local prices vary too much to publish honestly. Enter your supplier's price and the result is costed with it.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

Regulatory standards & verification citations

  • Compacted hot-mix asphalt has a commonly-cited average density of about 145 lb per cubic foot
  • Residential asphalt driveways are typically 2-3 in thick over a compacted gravel base

Still deciding? Gravel vs Asphalt Driveway — the factors that actually differ, with no invented prices.

Frequently asked questions

Does this include the gravel base?
No — this estimates asphalt only. See the Gravel Driveway Calculator for base material, which is typically installed under the asphalt layer.
How thick should my asphalt be?
2-3 in is standard for passenger vehicles. Consider 3-4 in for driveways that will regularly carry heavier vehicles like RVs or trucks.
Does temperature affect asphalt installation?
Yes — asphalt needs to be installed while hot and compacted before it cools, so professional installation is time-sensitive and typically not a DIY project the way gravel or pavers can be.
