Estimate compacted asphalt volume, weight, short tons, metric tonnes, dynamic coverage, extra material, loose-volume information, and optional material cost.
Area and final compacted depth produce compacted volume. Editable compacted density converts that volume to mass.
Extra material is applied once to volume and mass after all geometry. Optional loose-volume factor changes only the informational loose volume; mass is not multiplied again.
The initial 145 lb/ft³ density and 1.2 loose-volume factor are editable starting values, not universal asphalt properties. The loose factor is used only when optional loose-volume information is enabled.
area = length × widtharea = π × (diameter ÷ 2)²area × compacted depth × quantitycompacted volume × compacted densitybase quantity × (1 + extra % ÷ 100)mass per ton ÷ density ÷ compacted depthA 50 × 20 ft driveway at 3 in depth has 250 ft³ compacted volume. At an entered 145 lb/ft³ it weighs 36,250 lb or 18.125 short tons; with 5% extra, 19.031 short tons.
A 2,000 ft² area at 2 in compacted depth has 333.333 ft³ base volume. At an entered 145 lb/ft³, that is 24.167 short tons; with 5% extra, the result is 25.375 short tons.
A 500 m² area at 50 mm depth has 25 m³ volume. At an entered 2,300 kg/m³ it weighs 57.5 tonnes; with 5% extra, 60.375 tonnes.
Enter final compacted asphalt depth, not loose lift depth.
The initial 145 lb/ft³ value is editable; confirm compacted mix density with the supplier, mix design, or project specification.
The optional 1.2 starting value is editable and informational. Replace it with project-specific information rather than treating it as a universal compaction factor.
Coverage per ton is calculated from the selected density and depth rather than a universal lookup.
Mix materials and achieved compaction affect in-place density. FHWA examples demonstrate that mixtures made with different aggregates can have significantly different densities. The calculator normalizes user-entered lb/ft³ or kg/m³ to kg/m³.
A US short ton is 2,000 lb. A metric tonne is 1,000 kg; results label both explicitly.
Optional loose-volume mode multiplies recommended compacted volume by an editable, project-dependent factor for information only. It is disabled initially. With compacted density, calculated mass is conserved and is not multiplied by that factor.
US pricing uses recommended short tons; metric pricing uses recommended metric tonnes. Delivery, trucking, labor, equipment, preparation, grading, disposal, and taxes are excluded.
Calculate area times compacted depth, multiply by the entered compacted density, and add the selected allowance.
Compacted volume is multiplied by user-entered density and converted to short tons or metric tonnes.
It depends on density; this calculator derives weight from your editable density.
Weight varies by mix and compaction; use supplier or specification density when available.
Enter the compacted density for the actual mix. The initial 145 lb/ft³ value is an editable starting value only.
At fixed area and density, volume and tonnage increase directly with depth.
Coverage is calculated dynamically from selected depth and density.
A short ton is 2,000 lb; a metric tonne is 1,000 kg.
Project conditions vary; choose the editable allowance suitable for planning.
Depth and density are treated as compacted values. Optional loose volume uses an editable factor for information only and does not change mass.
No. Optional cost is asphalt material only.
