Asphalt Cost and Material Chart
Example Data Table
| Project | Length | Width | Thickness | Square Yards | Estimated Tons |
|---|---|---|---|---|---|
| Small driveway | 40 ft | 12 ft | 3 in | 53.33 | 6.53 |
| Parking strip | 80 ft | 18 ft | 4 in | 160.00 | 26.10 |
| Round pad | 30 ft diameter | 3 in | 78.54 | 9.61 | |
Formula Used
Rectangle area: Area in square feet = length × width.
Circle area: Area in square feet = π × radius².
Square yards: Square yards = square feet ÷ 9.
Thickness in feet: Thickness feet = thickness inches ÷ 12.
Volume: Cubic feet = square feet × thickness feet.
Cubic yards: Cubic yards = cubic feet ÷ 27.
Raw tons: Tons = cubic feet × density ÷ 2,000.
Final tons: Final tons = raw tons × (1 + waste percentage ÷ 100).
Total cost: Material cost + labor cost + base cost + tax or overhead.
How to Use This Calculator
Select the project shape first. Use rectangle for most driveways, lanes, and parking areas. Use circle for round pads. Use known square feet when your plan already includes the measured area.
Enter thickness in inches. Use compacted thickness, not loose material depth. Add density, waste, and price values. Then press the calculate button. The result section will show square yards, cubic yards, tons, and estimated cost.
Advanced Asphalt Square Yard Planning
Why Square Yards Matter
Asphalt work often starts with a surface measurement. Contractors may quote paving by square yard. Material suppliers may quote by ton. This calculator connects both units. It helps you move from field measurements to ordering numbers. A clear square yard value also improves bidding, planning, and comparison.
Measure the Surface Carefully
Start with the paved shape. For a rectangle, measure length and width in feet. For a circle, measure the full diameter. For mixed areas, split the surface into smaller shapes. Add each area together. Then use the custom square feet option. Careful measuring reduces waste and avoids shortages.
Understand Thickness
Thickness strongly changes the final tonnage. A thin overlay needs less material. A new driveway usually needs more depth. Heavy traffic areas may need a thicker layer. Always enter compacted thickness. Loose asphalt settles during rolling, so the delivered amount must match the finished layer.
Use Density and Waste
Asphalt density can vary by mix type. A common planning value is about 145 pounds per cubic foot. Your supplier may give a better value. Waste covers edges, low spots, truck loss, and field changes. Small jobs may need a higher waste percentage than large uniform areas.
Estimate Budget Clearly
The calculator separates material, labor, base preparation, and tax. This makes the estimate easier to review. Material cost depends on tons. Labor and base costs depend on square yards. The final cost per square yard helps compare multiple quotes. It also helps decide if changing thickness or area size is affordable.
Plan Before Ordering
Use the results as a planning estimate. Confirm local mix design, truck minimums, compaction needs, and site conditions before buying. Drainage, grading, and base quality can change the real cost. A strong estimate gives you a better starting point for contractor discussions.
FAQs
1. How do I calculate asphalt square yards?
Find the area in square feet first. For a rectangle, multiply length by width. Then divide square feet by 9. The result is the area in square yards.
2. Why does the calculator ask for thickness?
Thickness converts surface area into volume. Asphalt tonnage depends on volume and density. A thicker layer needs more cubic feet and more tons.
3. What density should I use for asphalt?
A common planning value is 145 pounds per cubic foot. Actual density can change by mix design. Ask your supplier for the best project value.
4. Should I include waste?
Yes. Waste covers trimming, uneven ground, edge loss, and small measurement errors. Many projects use 5% to 10%, but difficult areas may need more.
5. Does square yard cost include labor?
It depends on the quote. This calculator separates material, labor, and base preparation. That makes the total estimate easier to adjust.
6. Can I use this for a parking lot?
Yes. Measure the parking lot in sections. Add the square feet together. Then use the custom area option for a complete estimate.
7. Is cubic yard the same as square yard?
No. Square yard measures surface area. Cubic yard measures volume. Asphalt ordering often needs both area and depth to estimate tons.
8. Is this estimate exact?
No estimate is exact. Real results depend on grading, compaction, mix density, haul loss, and local pricing. Use it for planning and comparison.
