Asphalt Tonnage Calculator

Plan paving confidently with precise tons, volumes, and truck counts for crews. Toggle US or metric, adjust density presets, and waste allowances per project. Add multiple areas, per‑segment thicknesses, and notes for complex jobs. Export itemized results to CSV or PDF for documentation and team sharing. Smart defaults, clear math, fast estimates every time.

Formula used

US mode

For each segment: Area(ft²) = Width(ft) × Length(ft)
Thickness(ft) = Thickness(in) ÷ 12
Volume(ft³) = Area × Thickness(ft)
Mass(lb) = Volume(ft³) × Density(lb/ft³)
Tons = Mass(lb) ÷ 2000
After applying waste: Tons × (1 + Waste% ÷ 100).

Metric mode

For each segment: Area(m²) = Width(m) × Length(m)
Thickness(m) = Thickness(mm) ÷ 1000
Volume(m³) = Area × Thickness(m)
Mass(kg) = Volume(m³) × Density(kg/m³)
Tonnes = Mass(kg) ÷ 1000
After applying waste: Tonnes × (1 + Waste% ÷ 100).

How to use this calculator
  1. Choose the unit system suitable for your project.
  2. Select a density preset or enter a custom density.
  3. Set a reasonable waste percentage for round‑off and field variability.
  4. Add one or more segments; enter width, length, and thickness.
  5. Review live totals for area, volume, mass, and truck count.
  6. Export itemized results to CSV or PDF for your records.
  7. Validate outputs against project specifications and mix submittals.
FAQs

A common planning value is 145 lb/ft³ (≈2322 kg/m³). Confirm actual density from the supplier’s submittal for your precise mix and temperature.

Enter the compacted thickness specified on drawings. Waste percentage accounts for typical laydown variability and small overruns in the field.

It’s a planning estimate that divides total tons by entered truck capacity and rounds up. Confirm with actual haul limits, routes, and cycle times.

Approximate irregular areas by splitting them into rectangles as separate segments. You can add unlimited segments and include notes per line.

Planners often use 5–10% depending on project tolerance, geometry, handwork, and tie‑ins. Adjust to match your organization’s norms and previous data.

US mode uses ft/in with mass in short tons. Metric mode uses m/mm with mass in metric tonnes. Density units change accordingly and calculations update instantly.

Use the CSV export for spreadsheets or the PDF export for quick summaries. Attach these files to submittals, emails, or internal planning documents.
