Calculation trace
Volume = total area × depth × quantity
Mass = 5.000 m³ × 2320 kg/m³ = 11600 kg
Required = 11.60 t × (1 + 5/100) = 12.18 t
Volume = total area × depth × quantity
Mass = 5.000 m³ × 2320 kg/m³ = 11600 kg
Required = 11.60 t × (1 + 5/100) = 12.18 t
Quantity estimate only. Verify dimensions and supplier density. Layer thickness must come from the applicable pavement design or project requirements.
Asphalt Material Estimate
Calculate compacted asphalt from the total surface area, design thickness, selected density and allowance. The result includes volume, mass, delivery loads and material cost.
Why Compacted Density Matters
Asphalt is normally ordered by mass, while drawings specify area and compacted thickness. Density connects those quantities. Use project mix information because density varies between mixes.
Thickness Is a Design Input
The calculator does not choose pavement thickness. Enter the thickness from project requirements or a qualified pavement design. Presets exist only to speed up quantity comparisons.
Allowance and Delivery
The allowance can cover compaction, leveling and practical ordering variation. It should be selected deliberately rather than treated as a universal waste rate.
Asphalt Calculator FAQ
How many tonnes of asphalt do I need?
The calculator multiplies paved area by compacted thickness and material density, then applies the entered allowance.
What asphalt density should I use?
Use the project mix or supplier's compacted density. The presets are broad examples and can be overridden.
Can I calculate more than one paved area?
Yes. Add multiple rectangular, circular or known-area sections and the calculator totals them.
What thickness should asphalt be?
Thickness depends on pavement design, traffic, subgrade, climate and mix. Quick values in the tool are examples only, not engineering recommendations.
Can taxes and delivery be included?
The current cost estimate multiplies material by the entered price basis. Add delivery or tax to the unit price if you want a combined planning allowance.
How are truck loads calculated?
Required tonnes are divided by the payload you enter and rounded up to a whole load.
