What the Calculator Handles
Project Dimensions
Length, width, and thickness with flexible unit toggles (m/ft, mm/in). Supports both US Imperial and Metric systems.
Mix Properties
Bitumen content (%) and mix density (kg/m³ or lb/ft³) for precise material calculations.
Cost Estimation
Optional price per tonne input for quick budgetary figures and project cost planning.
Clear Results
Instant outputs showing volume, weight (tonnes & kg), truck loads, and time estimates.
Our Principles
Accuracy First
Our calculations use NIST-standard conversion constants and industry-accepted formulas. The math is transparent and defensible for pre-bid planning and site checks.
Privacy by Default
Use the calculator without creating an account. We keep data collection minimal and straightforward—your project data stays in your browser.

Accessibility
Keyboard navigation, clear focus states, and readable typography. Built for everyone.
What's Next
We're continuously improving. Here's what's on our roadmap:
- Saved Scenarios — Compare multiple project configurations side-by-side
- Export to CSV/PDF — Download your calculations for reports and documentation
- More Calculators — Prime/tack coat coverage, emulsion rates, and asphalt layer take-offs
- Localization — Unit presets for regional standards (UK, AU, EU)
- Dark Mode — For those late-night project planning sessions
