Bitumen Calculator

Estimate bitumen volume and weight for road surfacing, driveways, and paving — with waste factor and drum counts.

Coverage rate is common for tack/prime/spray applications. Thickness is for volume-style estimating.

Enter application rate. If you have a spec sheet, use that value.

Extra for handling losses and surface variation.

Typical paving-grade bitumen ~1010–1050 kg/m³ (varies by grade & temperature).

Container counts are rounded up to whole containers.

Bitumen Calculator – Volume, Weight & Drums

Use this tool to estimate how much bitumen you need for paving and surfacing. Enter the project area and thickness, add a waste allowance, and the calculator returns volume in both metric and imperial units, estimated weight, and how many 20 L or 200 L containers to order.

Features

How It Works

The calculator multiplies area by thickness to get volume, applies your waste percentage, then converts to weight using the selected density. Results are shown in m³ and yd³ for volume, and tonnes and short tons for weight.

FAQs

How do you calculate bitumen quantity?
Area × thickness = volume. Apply waste, then multiply by density to get weight.

What density should I use?
If you don’t have a spec sheet, 1,010–1,050 kg/m³ is typical for paving-grade binders.

Liters to drums?
Divide total liters by your chosen container size (20 L or 200 L) and round up.

Important Estimate Disclaimer

Estimates are intended for general planning only and should not be considered paving or engineering specifications. Actual quantities may vary based on compaction, base preparation, climate, and traffic load.

Refer to our Methodology and Data Sources for calculation assumptions.

Asphalt depth, sub-base stability, and drainage conditions may materially impact performance and required material thickness.
