Work out asphalt tonnage instantly with clear inputs, formula shown and shareable results.
For a linear job it is quicker to work from length and width than from a measured area. Tonnage is length times width times thickness times compacted density. The tonnes per kilometre figure is useful for programme planning because it converts directly into daily paving output.
Tonnage
Tonnes = length x width x thickness m x density / 1000
Tonnes = length x width x thickness m x density / 1000. For a linear job it is quicker to work from length and width than from a measured area.
No, tack coat is measured separately in litres per square metre, typically 0.2-0.4 L/m² of emulsion, and is ordered as a distinct item.
This calculator takes 4 inputs: Road length, Road width, Layer thickness, Compacted density. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
