Tons of Asphalt Millings per 100 Feet of 20 ft Road
Tons of asphalt millings per 100 feet of 20 foot road: about 32 tons at 4 inches deep. The strip is 20 ft × 100 ft = 2,000 square feet. On a job this long, half an inch of extra depth adds a lot of tons.
Volume and tonnage calculator →Tons by depth
| Depth | Tons | Truckloads (~14 t) |
|---|---|---|
| 3 in | 24 | 2 |
| 4 in | 32 | 3 |
| 6 in | 48 | 4 |
| 8 in | 64 | 5 |
The math
- Area: 20 × 100 = 2,000 sq ft.
- Volume at 4 in: 2,000 × 0.333 = 667 cu ft (25 cubic yards).
- × 1.3 tons per yard = 32 tons.
What goes into the section
At 20 feet wide, two cars can meet with care. Asphalt millings are ground-up old pavement. When compacted and warmed by sun they bind into a fairly firm surface, which is why they are popular for rural drives and lots. Crown the surface so water sheds to ditches on both sides.
Practical notes
- Phasing. Large tonnages are delivered over days; schedule spreading and compaction to keep up with trucks.
- Waste. Allow 5 to 10 percent.
- Hauling. Distance from the quarry or plant often costs as much as the material on long jobs; see asphalt hauling cost per ton.

Good and poor uses for asphalt millings
Best suited to:
- Rural driveways and farm lanes
- Parking areas where a dust-free surface is wanted
- Low-cost base under a future paved surface
Think twice for:
- Areas near wells or streams where local rules limit them
- Decorative or barefoot areas
- Jobs needing a uniform, clean look
Quick reference numbers
- Per inch over 100 sq ft: about 0.40 tons of asphalt millings (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.0 tons.
- Another size for comparison: a 20x25 area at 2 inches takes about 4.0 tons.
- Weight used here: about 1.3 tons per cubic yard.
Common estimating mistakes
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
