Terms of use

Last updated: July 2026

By using bitumencalculator.org you accept the terms below. They are short on purpose.

• The tools are free, and they are estimates. Every calculator here is provided as-is for planning and checking. It is not a substitute for a pavement design, a job mix formula, or a qualified engineer.
• Your specification always wins. Our defaults come from published guidance. If a figure on this site disagrees with the document you are working to, follow your document.
• Check the result before you order. We take no liability for material ordered, money spent, or work carried out on the basis of a number from this site.
• Use it, don’t copy it. Run the calculators as often as you like and share the links freely. Republishing the content, code or tables as your own is not permitted.
• Things change. Tools, figures and these terms may be updated at any time without notice.
