Asphalt Calculation Formula
Example Calculation:
For a 30ft × 20ft driveway at 4 inches deep:
Volume = 30 × 20 × 0.33 = 198 cubic feet
Tonnage = (198 × 145) ÷ 2,000 = 14.36 tons
Frequently Asked Questions
Get answers to common asphalt calculator questions
How much asphalt do I need for a 1,000 sq ft driveway?
For a 1,000 sq ft driveway at 4 inches thick, you’ll need approximately 16-18 tons of asphalt. This equals about 12.35 cubic yards. Total cost typically ranges from $1,600-$3,600 depending on your location and asphalt type.
How many square feet does 1 ton of asphalt cover?
1 ton of asphalt covers approximately 40-80 square feet, depending on the thickness. At 3 inches thick, 1 ton covers about 80 sq ft. At 6 inches thick, 1 ton covers about 40 sq ft.
What's the minimum thickness for an asphalt driveway?
The minimum thickness for a residential asphalt driveway is 3 inches. However, 4-6 inches is recommended for areas with heavy traffic or cold climates to prevent cracking and ensure longevity.
How accurate is this asphalt calculator?
Our calculator uses industry-standard formulas with a density of 145 lbs per cubic foot, which is the professional standard. Results are accurate within 5% for most applications. We recommend adding 5-10% extra for waste and compaction.
What's the difference between hot mix and cold mix asphalt?
Hot mix asphalt (HMA) is heated during production and provides superior durability and longevity. Cold mix asphalt doesn’t require heating and is primarily used for repairs and patches. Hot mix is recommended for new driveways and parking lots.
How much does asphalt cost per ton in 2025?
Asphalt costs range from $70-$200 per ton in 2025, depending on your location, asphalt type, and local market conditions. Hot mix asphalt typically costs $100-$150 per ton, while specialty mixes may cost more.
Can I use this calculator for parking lots?
Yes! Our calculator works for driveways, parking lots, roads, and any asphalt paving project. For commercial parking lots, consider using 6-8-inch thickness for heavy-duty applications and truck traffic.
Do I need a base layer under asphalt?
Yes, a proper base is essential for asphalt longevity. Use 4-8 inches of compacted crushed stone or gravel base, depending on soil conditions. Sandy soil requires 4 inches, while clay soil needs 6-8 inches of base.
