Density Information
Standard Densities
Hot Mix Asphalt: 110 lbs/(SY·IN) or 2.0 tons/yd³
Warm Mix Asphalt: 105 lbs/(SY·IN) or 1.9 tons/yd³
Recycled Asphalt: 102 lbs/(SY·IN) or 1.85 tons/yd³
Compaction Factor
Typically 5-15% additional material is needed to account for compaction during paving. Our calculator uses 10% by default, which is standard for most projects.
Unit Conversions
• 1 ton = 0.907 tonnes
• 1 cubic yard = 27 cubic feet
• 1 square yard = 9 square feet
How to calculate asphalt for driveway
Calculating the correct amount of asphalt for your driveway is essential for accurate budgeting and material ordering. Follow these step-by-step instructions to determine exactly how much asphalt you need:
Step 1: Measure Your Driveway
- Length: Measure from the street to your garage or parking area
- Width: Measure the widest point of your driveway
- Thickness: Standard residential driveways need 2-3 inches of asphalt
Step 2: Calculate Square Footage
Multiply length × width to get your total square footage. For example: 100 feet × 12 feet = 1,200 square feet.
Step 3: Determine Asphalt Volume
Convert thickness to feet (3 inches = 0.25 feet), then multiply: Square footage × thickness in feet = cubic feet. Convert to cubic yards by dividing by 27.
Step 4: Account for Compaction
Add 10-15% extra material to account for compaction during installation. This ensures you have enough asphalt for proper coverage and thickness.

How much to re-asphalt a driveway
Re-asphalting a driveway involves several cost factors beyond just the material. Here's a comprehensive breakdown of what you can expect to pay for a complete driveway resurfacing project:
Material Costs
- Asphalt: $80-150 per ton (varies by region and quality)
- Hot Mix Asphalt: Most expensive but longest lasting
- Warm Mix Asphalt: Mid-range option with good durability
- Cold Mix Asphalt: Budget option for temporary repairs
Labor and Equipment Costs
- Removal of old asphalt: $1-3 per square foot
- Base preparation: $2-5 per square foot
- Installation: $3-7 per square foot
- Compaction and finishing: $1-2 per square foot
Total Project Costs
- Small driveway (400 sq ft): $1,600 - $4,000
- Medium driveway (600 sq ft): $2,400 - $6,000
- Large driveway (1,000 sq ft): $4,000 - $10,000
Factors Affecting Cost
- Geographic location and local material costs
- Condition of existing base and drainage
- Accessibility and site preparation requirements
- Thickness of new asphalt layer needed
- Additional features like edging or sealing
