How to Use the Calculator

1

Select Your Project Type

Choose from predefined project types or use custom settings:

  • Driveway: Standard residential driveways (2-3 inches depth)
  • Parking Lot: Commercial parking areas (4-5 inches depth)
  • Road: Local roads and streets (6-8 inches depth)
  • Pathway: Walkways and trails (2-3 inches depth)
2

Enter Project Dimensions

Measure and input your project dimensions:

  • Length: Measure the longest side of your project area
  • Width: Measure the shortest side of your project area
  • Depth: Enter the desired asphalt thickness
Tip: Use a measuring tape or laser measure for accurate dimensions. For irregular shapes, break the area into rectangles and calculate each separately.

Expert Tips

Best Installation Practices

For optimal results, install asphalt when temperatures are between 50°F and 90°F. Ensure proper drainage with a 2% slope away from structures.

Subgrade Preparation

A properly prepared subgrade is critical for longevity. Include a 4-6 inch compacted aggregate base for best results.

Maintenance Schedule

Seal coat every 2-3 years. Repair cracks promptly to prevent water infiltration and extend pavement life.

Technical Information

Asphalt is a composite material consisting of mineral aggregate bound together with bitumen. The composition varies by application:

  • Hot Mix Asphalt (HMA): The most common type, composed of 95% aggregate and 5% bitumen, heated to 300-350°F during application.
  • Warm Mix Asphalt (WMA): Similar to HMA but produced at lower temperatures (250-275°F), reducing energy consumption and emissions.
  • Cold Mix Asphalt: Made with emulsified or cutback asphalt, suitable for low-volume roads and repairs.
  • Porous Asphalt: Contains larger aggregate sizes to create voids for water drainage, beneficial for reducing runoff.

Accurate asphalt calculations involve several key formulas:

  1. Volume Calculation: Length × Width × Depth
  2. Unit Conversion: 1 cubic yard = 27 cubic feet
  3. Weight Calculation: Volume × Density (typically 145 lbs/cubic foot)
  4. Waste Factor: Total volume × (1 + Waste%) to account for spillage and compaction
  5. Cost Estimation: Weight (tons) × Price per ton

Our calculator uses these industry-standard formulas with precision adjustments for different asphalt types.

Asphalt installations typically follow these industry standards:

  • ASTM D6927: Standard Test Method for Marshall Stability and Flow of Asphalt Mixtures
  • AASHTO M320: Standard Specification for Performance-Graded Asphalt Binder
  • Superpave Specifications: Modern performance-based specifications for asphalt mixtures

Local specifications may vary, with state Departments of Transportation typically providing region-specific guidelines that account for climate, traffic load, and other regional factors.
