Pick units and enter area and thickness. We estimate volume, tons, trucks, base aggregate, tack coat, and cost.
Overview
Planning asphalt work shouldn’t require a spreadsheet. This calculator turns driveway and parking-lot dimensions into clear numbers:
compacted thickness, material volume, tons, truckloads, and optional base aggregate and tack coat. Switch between US and metric,
set your own density and waste allowance, and add pricing to see a quick cost snapshot. When you’re done, export a CSV you can
share with a supplier or drop into a quote.
Use it for new installs, overlays, or patching. Enter a single rectangle or break irregular sites into multiple areas and we’ll
total everything for you. If your spec calls for a binder layer under the surface lift, enable it and the tool will calculate
each lift separately. Base stone and tack are optional but useful when you’re pricing from subgrade up or planning a mill-and-fill.
Heads-up: results are estimates. Real-world outcomes depend on mix design, compaction, weather, base prep, and crew technique.
Confirm local specs and supplier guidance, then round up to avoid short loads and downtime.

How to use this asphalt calculator
Select Units (US or Metric) and set Waste, Truck capacity, and Asphalt density if needed.
Enter Layers & pricing: surface thickness (and binder if used) with optional price per ton to estimate cost.
(Optional) Add Aggregate base and Tack coat with densities and pricing.
Choose Single rectangle or Multiple areas. Enter dimensions and click Calculate.
Review Summary and Materials, then Download CSV for your records or quote.
Tip: For irregular shapes, break the site into rectangles and use “Multiple areas.”
What your results mean
Asphalt tons: Computed from area × thickness × asphalt density (default 145 lb/ft³), plus your waste allowance.
Truckloads: Asphalt tons ÷ your truck capacity. Always confirm your hauler’s max legal load.
Base aggregate: If enabled, we calculate tons using your base thickness and density (default 100 lb/ft³).
Tack coat: Gallons estimated from your rate per 1000 ft². Coverage varies by surface condition.
Total cost: Based on the per-ton/per-gallon prices you enter. Delivery, taxes, mobilization not included.
Assumptions & defaults
Density: Asphalt 145 lb/ft³ by default; base 100 lb/ft³. Adjust for your local mix and compaction.
Waste: Added after volume calculations. Typical range 5–10% depending on edges and handwork.
Thickness: Enter compacted thickness (not loose lift thickness).
Units: Metric inputs convert to US internally (m→ft, cm→in) to keep math consistent.
Rounding: Truckloads are rounded up. Costs shown when prices are provided.
FAQ
What thickness should I use for a driveway vs. a parking lot?
Driveways often use 2–3 in surface; light-duty parking 3–4 in; heavy-duty areas may add a binder layer. Always follow local specs.
What density should I enter?
145 lb/ft³ is common for compacted hot-mix asphalt. Your supplier can provide a more accurate value for your mix.
Does the calculator include compaction?
Yes. Enter compacted thickness. If you only know loose thickness per lift, convert to compacted thickness before entering.
Are delivery and mobilization included in cost?
No. Enter per-ton and per-gallon material prices. Add trucking, mobilization, and taxes separately in your estimate.
