Asphalt Parking Lot Calculator
Estimate multiple parking areas with separate surface and binder lifts, truckloads, material cost, print, and CSV output.
Parking lot areas and lifts
Separate surface and binder quantities for every area.
Parking lot estimate
| Area | Surface | Binder | Total |
|---|---|---|---|
| Main parking area | 241.67 | 362.50 | 604.17 US tons |

Order totals include the entered 0% allowance; area rows show calculated base quantities.
Result scope
Each zone calculates area × compacted lift thickness × lift density. Surface and binder totals remain separate before the combined truckload and material-cost estimate.
Formula
Worked example
A 200 × 100 ft area has 20,000 sq ft. At 2 inches and 145 lb/ft³, the surface lift is about 241.67 US tons. A separate 3-inch binder lift at the same assumed density is about 362.50 tons.
Reference at 145 lb/ft³
| 1,000 sq ft lift | US tons | Metric tonnes |
|---|---|---|
| 1.5 in | 9.06 | 8.22 |
| 2 in | 12.08 | 10.96 |
| 3 in | 18.13 | 16.44 |
Common mistakes
- Including islands twice or failing to subtract excluded areas.
- Combining surface and binder without retaining lift-specific mix and density assumptions.
- Using quantity output as a pavement design or installed bid.
Contractor and supplier checklist
- surveyed net area, lift plan, mix designations, compacted densities, and allowance basis;
- milling, base, drainage, transitions, curbs, markings, traffic control, and testing scope;
- plant production, payload, delivery sequence, tonnage tickets, and rejected-load procedure.

The FHWA asphalt density report explains why mixture density and compaction are project variables. Start with the density guide, compare the core asphalt calculator and truckload calculator, then review treatment scope in the pavement decision guide.
