How to Convert SY to Tons of Asphalt

To convert asphalt SY to tons, use this standard industry formula:

Tons = Square Yards × Thickness (inches) × 0.0031

This asphalt calculator SY to tons formula uses the average asphalt density factor (0.0031) commonly applied in paving projects.

Asphalt SY to Tons Example

If you need to convert SY to ton asphalt for a project:

Calculation:

1,000 × 3 × 0.0031 = 9.3 tons

This simple asphalt conversion SY to tons method helps contractors order the correct amount of asphalt.

Convert Tons to SY in Asphalt

If you want to convert tons to SY in asphalt, use this reverse formula:

Square Yards = Tons ÷ (Thickness × 0.0031)

This helps determine how much area a certain amount of asphalt can cover.

Frequently Asked Questions

How do you convert square yards to tons of asphalt?
To convert SY to tons: Area (SY) × Thickness (inches) × 0.055 = Tons. For example, 100 SY at 2 inches thick = 100 × 2 × 0.055 = 11 tons. The multiplier 0.055 accounts for asphalt density of 110 lbs per square yard per inch.
How many square yards in a ton of asphalt?
At 2 inches thick, 1 ton covers approximately 18 square yards. At 3 inches, 12 square yards. At 4 inches, 9 square yards. The coverage decreases as thickness increases.
What is the formula for asphalt tonnage?
Tons = (Length (ft) × Width (ft) × Thickness (inches) × 145) ÷ 2000 ÷ 27. Or simplified: SY × Thickness (inches) × 0.055 = Tons. The 0.055 factor comes from 110 lbs per SY per inch.
How thick should asphalt be for a driveway?
Residential driveways typically require 2-3 inches of compacted asphalt over a 4-8 inch base. For heavy vehicle traffic, increase to 3-4 inches. Commercial parking lots need 3-5 inches depending on expected loads.
What is the density of asphalt?
Standard asphalt density is 145 lbs per cubic foot, or approximately 110-115 lbs per square yard per inch of thickness. This can vary slightly based on mix design and aggregate type.
How do I calculate asphalt for a parking lot?
Measure total area in square yards, multiply by desired thickness in inches, then multiply by 0.055 for tons. Add 5-10% for waste and compaction. For large lots, consider different thicknesses for car vs truck areas.
