Disclaimer

The arithmetic is exact. The answer is only as good as what you put in — and your specification always outranks this site.

These are estimates, not designs

The tools here help you plan and sanity-check an order. They do not design a mix, size a pavement for traffic, or replace a qualified engineer.

Defaults are starting points

Densities, binder percentages and spray rates come from published guidance and cover a typical case. Your job mix formula, supplier certificate and project specification are the real numbers. Enter them.

Check before you order

Hot mix cannot be returned. Verify every figure against your documents and site measurements before you place an order or begin work.

No liability

The site is provided as-is, free of charge. We accept no responsibility for material ordered, costs incurred, delays or damage arising from use of these calculators.
