Formula

Asphalt calculation formula:

Volume (cubic feet) = Length × Width × (Depth/12) Weight (tons) = Volume × 145 lbs/ft³ / 2000

Tips for Accurate Measurements

  • Install a 4-6 inch gravel base before asphalt
  • Ensure proper drainage with 1-2% slope
  • Asphalt must be installed in warm weather (above 50°F)
  • Avoid driving on new asphalt for 24-48 hours
  • Seal coat every 2-3 years for longevity
