Calculating Bitumen Quantity for Driveways

Residential driveways require the same mathematical precision as commercial roads, just on a smaller scale. Whether you are laying a fresh surface or applying a heavy seal coat, knowing your exact quantity of bitumen per square metre prevents mid-project supply runs.

Standard Driveway Dimensions

A typical two-car residential driveway is roughly 20 feet wide by 20 feet long (400 square feet). If you are laying a standard 2-inch compacted layer, manual math can get messy when converting feet to cubic yards and then to tonnes.

How to Estimate Quickly

Instead of manually converting imperial dimensions into metric densities, simply open the Bitumen Calculator:

1. Click the "Small Driveway" Quick Preset at the top of the tool.
2. Adjust the length and width to match your specific property lines.
3. Keep the waste contingency at 5% to account for uneven dirt sub-bases.

The tool will instantly output your required material in both loose volume (cubic yards) and total weight (tons).
