What is an Asphalt Yield Calculator?
An Asphalt Yield Calculator is a tool used to determine the volume of asphalt that can be obtained from a given weight of asphalt material. This is essential for construction projects to estimate material requirements and ensure proper planning.
How to Use the Asphalt Yield Calculator
- Enter the Weight of Asphalt in pounds (lb) or kilograms (kg)
- Enter the Density of Compacted Asphalt in lb/ft³ or kg/m³
- Click Calculate to get the asphalt yield in cubic feet (ft³)
Asphalt Yield Formula
The asphalt yield is calculated using the formula:
$$\text{Asphalt Yield} = \frac{\text{Weight of Asphalt}}{\text{Density of Compacted Asphalt}}$$
Where:
- Weight of Asphalt is the total weight of asphalt material
- Density of Compacted Asphalt is the density after compaction (typically 140-150 lb/ft³)
Example Calculation
Given:
- Weight of asphalt = 60,000 lbs
- Density of compacted asphalt = 150 lbs/ft³
Calculation:
$$\text{Asphalt Yield} = \frac{60000}{150} = 400 \text{ ft}^3$$
The asphalt yield is 400 ft³.
Common Asphalt Densities
- Hot Mix Asphalt (HMA): 140-150 lb/ft³
- Warm Mix Asphalt (WMA): 145-155 lb/ft³
- Cold Mix Asphalt: 130-140 lb/ft³
Applications
- Estimating material requirements for paving projects
- Planning asphalt delivery and storage
- Calculating costs based on volume
- Quality control in asphalt production
- Road construction and maintenance planning
