Terms of Use

Every figure produced by this site's calculators — tonnage, volume, cost, or otherwise — is a planning-stage estimate based on standard formulas and typical material densities. It is not a structural engineering calculation, a binding quote, or a substitute for advice from a licensed contractor, paving engineer, or your local building authority. Actual material needs and project cost vary based on soil conditions, drainage, regional pricing, supplier mix design, and other site-specific factors we cannot account for.

We make a good-faith effort to keep formulas and reference data accurate, but we provide this site "as is" without warranty of any kind. We are not liable for material shortages, cost overruns, project delays, or any other outcome resulting from reliance on these calculators.

You may use this site for personal or professional project planning. You may not scrape, republish, or redistribute our calculators, copy, or page content without permission, or use automated tools to overload our servers.

This site contains links to third-party retailers, suppliers, and reference sources. We don't control and aren't responsible for the content, accuracy, or practices of those external sites.

We may update these terms as the site changes. Continued use of the site after an update means you accept the revised terms.

Questions about these terms can be sent to support@asphaltcalculatorhq.com.
