Asphalt Thickness & Base
Base depth is your compacted crushed stone or gravel section. Patch work often uses 0 if the base stays in place.
Material Assumptions
Keep the default unless your supplier gave you a specific density for the mix.
Optional Cost

Calculation Steps
This is a planning estimate. Actual yield will shift with the mix design, compaction, surface prep, and your local supplier.
How to Use This Calculator
1. Measure the footprint
Enter length and width for the paved area. Use feet for most residential jobs, or meters if your supplier quotes metric.
2. Match the section
Set the asphalt thickness and the compacted base depth. The presets cover driveways, parking pads, paths, and patch jobs.
3. Order by tons
Use the tons result when you call the plant, and the base cubic yards result when you order crushed stone or gravel.
Professional Paving Formulas & Calculation Steps
Example Calculation:
- • Driveway: 20 ft × 12 ft × 3 in of asphalt
- • Area = 240 sq ft
- • Asphalt depth = 3 in ÷ 12 = 0.25 ft
- • Raw asphalt volume = 240 × 0.25 = 60 cu ft
- • With 5% waste = 63 cu ft
- • Tons = 63 × 145 ÷ 2,000 = 4.57 tons
This estimate follows the standard paving workflow: calculate volume first, apply the mix density, then convert the final weight to tons.
