How this is worked out
Volume is area × laid depth, converted to tonnes at 2.36 tonnes per cubic metre for compacted asphalt.
Worked example
- Area 40 m²
- Laid depth 50 mm
40 × 0.05 = 2 m³, and 2 × 2.36 = 4.72
4.72 tonnes
Assumptions and limits
- The depth is the finished compacted depth.
- Density varies by mix, so the tonnage is an ordering guide rather than an exact weight.
