Q: How much asphalt do I need for a 1,000 sq ft driveway?

For a 4-inch depth, you'll need approximately 16-18 tons of asphalt, costing between $1,600 and $3,600 (depending on regional pricing).

Q: How many square feet does 1 ton of asphalt cover?

1 ton of asphalt covers 40-80 square feet, depending on the depth (e.g., 40 sq ft at 4 inches or 80 sq ft at 2 inches).

3 Simple Steps to Calculate Asphalt

Step 1: Enter Length, Width, and Depth (in feet/inches).
Step 2: Select asphalt type (Hot Mix, Cold Mix, Porous).
Step 3: Click “Calculate” to get tons, cubic yards, and total cost.

How Does the Asphalt Calculator Work?

Formula:
Volume (cubic feet) = Length × Width × Depth
Weight (tons) = (Volume × 145 lbs/cubic foot) ÷ 2,000

Example:
“For a 30ft x 20ft driveway at 4 inches deep:
Volume = 30 × 20 × 0.33 = 198 cubic feet
Tonnage = (198 × 145) ÷ 2,000 = 14.36 tons.”

How to Calculate Asphalt for Any Project

Need to pave a driveway, repair a road, or build a parking lot? Our free asphalt calculator eliminates guesswork by delivering precise estimates for:

Tonnage (short tons or metric tonnes)
Volume (cubic yards or meters)
Total Cost (based on asphalt price per ton)

Here’s how it works:

Measure Your Area: Enter length, width, and depth (inches or feet).
Select Asphalt Type: Hot Mix, Cold Mix, Porous, or Driveway Mix.
Calculate: Instantly get results + 5-6% overage to prevent shortages.

Pro Tip: Use our calculator’s unit converter to avoid “ton vs. tonne” errors. 1 ton = 2,000 lbs (U.S.), 1 tonne = 1,000 kg (metric).

Types of Asphalt & Best Uses

Type	Description	Ideal For
Hot Mix (HMA)	Durable, high-friction, heated for easy pouring	Highways, heavy-traffic roads
Warm Mix	Eco-friendly, low-temperature application	Night projects, cool climates
Porous Asphalt	Permeable design for drainage	Driveways, parking lots
Driveway Mix	Budget-friendly with gravel & sand	Residential driveways

What Impacts Asphalt Costs?

Material Type (Hot Mix vs. Cold Mix).
Thickness: 2-4 inches for driveways vs. 6+ inches for heavy traffic.
Regional Pricing: Asphalt costs 100−100−200 per ton.
Labor & Equipment: Excavation, grading, and compaction.
