Asphalt Millings Calculator
Estimate recycled asphalt millings from measured area, compacted thickness, and a project-specific placed bulk density.
Asphalt millings quantity inputs
Enter a project-specific placed bulk density.
Estimated quantity
Enter positive area, thickness, and density values.
What the result means
The calculator reports geometric compacted volume, base weight, and a separate order quantity after any allowance. It intentionally requires a placed bulk-density input instead of assuming one product value.
Formula
Worked example
For 1,000 sq ft at 3 inches using 120 lb/ft³: volume is 250 ft³ or 9.26 yd³; weight is 30,000 lb or 15 US tons before allowance.
Reference table at 120 lb/ft³
| Area | Depth | Volume | Weight |
|---|---|---|---|
| 1,000 sq ft | 2 in | 6.17 yd³ | 10.0 US tons |
| 1,000 sq ft | 3 in | 9.26 yd³ | 15.0 US tons |
| 1,000 sq ft | 4 in | 12.35 yd³ | 20.0 US tons |
Common mistakes
- Using hot-mix compacted density for variable millings.
- Confusing RAP in a plant mix with millings placed directly.
- Adding an unexplained allowance or assuming loose depth equals compacted depth.
Confirm with the supplier or contractor
- Material source, gradation, contamination, moisture, and placed bulk density;
- finished thickness, compaction method, drainage, edge restraint, and local use restrictions;
- truck payload, minimum order, and load rounding.
