About Us

Bitumen Calculator is a modern, easy-to-use tool for estimating the required quantities of bitumen and aggregates for pavement construction. Enter your project dimensions and material properties, and see results instantly—no account required.

What the calculator handles

• Project dimensions: length, width, and thickness with unit toggles (m/ft/km, m/ft, mm/cm/in).
• Mix properties: bitumen content (%) and mix density (kg/m³ or lb/ft³).
• Cost estimation (optional): add price per tonne ($/tonne) to get quick budgetary figures.
• Results panel: clear outputs designed for quick take-offs and “back-of-the-envelope” checks.

Our principles

• Accuracy first: the math should be transparent and defensible for pre-bid planning and site checks.
• Privacy by default: you can use the tools without creating an account; we keep data use minimal and straightforward.
• Speed & clarity: focused UI, mobile-friendly ergonomics, and sensible defaults.
• Accessibility: keyboard navigation, clear focus states, and readable typography.

What’s next

• Saved scenarios for side-by-side project comparisons.
• Export outputs to CSV/PDF.
• More construction calculators (e.g., prime/tack coat coverage, emulsion rates, and asphalt layer take-offs).
• Localization and unit presets for regional standards.
• Dark mode and further performance refinements.
