Asphalt Calculator – Estimate Asphalt Quantity and Cost Easily
What asphalt is made of?
The Asphalt Calculator is a fast and reliable tool designed to help you estimate the amount of asphalt (in tons or cubic yards) required for driveways, parking lots, roads, and other paving projects. Whether you are a contractor, engineer, or a homeowner taking on a DIY project, this calculator helps you plan efficiently by providing accurate material estimates.
What is Asphalt?
Asphalt, also known as bitumen, is a mixture of aggregates (like sand, gravel, and crushed stone) bound together with bitumen. It's widely used in road construction, parking lots, and driveways due to its durability and water-resistance.
How Does the Asphalt Calculator Work?
- Enter the dimensions of the area (length, width, and thickness).
- Select the unit of measurement (feet, meters, inches, etc.).
- Choose the asphalt density (default is 145 lb/ft³ or 2.32 g/cm³).
- Click “Calculate” to get the required volume and weight in tons or cubic yards.
Asphalt Volume and Weight Formula
To calculate the volume and weight of asphalt needed, we use the following formula:
Volume (ft³) = Length (ft) × Width (ft) × Thickness (in) ÷ 12 Weight (tons) = Volume (ft³) × Asphalt Density ÷ 2000
Standard asphalt density is approximately 145 lb/ft³. You can adjust this based on your asphalt type.
Example Calculation
Example: Driveway Paving
If your driveway is 20 feet long, 10 feet wide, and 4 inches thick:
Volume = 20 × 10 × (4 ÷ 12) = 66.67 ft³ Weight = 66.67 × 145 ÷ 2000 ≈ 4.83 tons
