How the Recycled Asphalt Millings Calculator Works

Crushed reclaimed asphalt pavement containing residual bitumen that binds and hardens under summer sun and roller compaction. Our Recycled Asphalt Millings Calculator computes exact geometric volume in cubic feet and cubic yards, then converts volume into US short tons (2,000 lbs) using the typical bulk density of Recycled Asphalt Millings (RAP) (2,835 lb/yd³ or 1.42 tons/yd³).

Mathematical Formula for Asphalt Millings:
1. Area (sq ft) = Length (ft) × Width (ft)
2. Volume (cu ft) = Area (sq ft) × [Depth (inches) ÷ 12]
3. Volume (cu yd) = Volume (cu ft) ÷ 27
4. Recommended Volume = Base Volume × (1 + 15% Ordering Adjustment)
5. Estimated Tons = Recommended Cubic Yards × 1.42 tons/yd³

Step-by-Step Worked Example

Example Project: 80 ft × 12 ft Area at 4 Inches Depth (+15% Adjustment)

Surface Area: 80 ft × 12 ft = 960 sq ft.
Base Volume: 960 sq ft × (4 ÷ 12) = 320.0 cu ft (11.85 cubic yards).
With +15% Ordering Adjustment: 11.85 yd³ × 1.15 = 13.63 cubic yards.
Weight in US Short Tons: 13.63 yd³ × 1.42 tons/yd³ = 19.32 tons (38,640 lbs).

Primary Applications & Contractor Best Practices

Dust-free rural and long driveways: Engineered for reliable coverage, drainage stability, and long-term performance.
Commercial equipment and semi-truck yards: Engineered for reliable coverage, drainage stability, and long-term performance.
Steep sloped driveways where loose gravel washes out: Engineered for reliable coverage, drainage stability, and long-term performance.
Parking lots and farm access roads: Engineered for reliable coverage, drainage stability, and long-term performance.

1,500 sq ft	15.09 t (10.65 yd³)	22.64 t (15.97 yd³)	30.19 t (21.30 yd³)	45.28 t (31.94 yd³)

Frequently Asked Questions

Multiply your project length (80 ft) by width (12 ft) to get area (960 sq ft). Multiply by depth in feet (4 in ÷ 12 = 0.33 ft) to get 320.0 cubic feet, then divide by 27 to get 11.85 base cubic yards. Adding a 15% ordering adjustment gives 13.63 yd³, which equals 19.32 US short tons at 2835 lb/yd³.

One cubic yard (27 cubic feet) of Recycled Asphalt Millings (RAP) weighs approximately 2,835 pounds, or 1.42 US short tons (105 lbs per cubic foot). Typical regional quarry densities range between 2,650 and 3,000 lb/yd³.

For most asphalt millings installations, a typical compacted depth is 4 inches (our default preset uses 4 inches). Always excavate soft organic topsoil and install woven or non-woven geotextile fabric before spreading aggregate.

At 1.42 tons per cubic yard, 1 US short ton equals 0.71 cubic yards (19.0 cu ft). That covers approximately 114 sq ft at 2" deep, 76 sq ft at 3" deep, and 57 sq ft at 4" deep.
