Tons of Asphalt Millings per 100 Feet of 28 ft Road
Tons of asphalt millings per 100 feet of 28 foot road: about 45 tons at 4 inches deep. The strip is 28 ft × 100 ft = 2,800 square feet. Shoulders, pullouts and turnarounds add to the total; measure them separately.
Volume and tonnage calculator →Tons by depth
| Depth | Tons | Truckloads (~14 t) |
|---|---|---|
| 3 in | 34 | 3 |
| 4 in | 45 | 4 |
| 6 in | 67 | 5 |
| 8 in | 90 | 7 |
The math
- Area: 28 × 100 = 2,800 sq ft.
- Volume at 4 in: 2,800 × 0.333 = 933 cu ft (35 cubic yards).
- × 1.3 tons per yard = 45 tons.
What goes into the section
At 28 feet wide, this is a two-lane road width. 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
Good uses:
- Rural driveways and farm lanes
- Parking areas where a dust-free surface is wanted
- Low-cost base under a future paved surface
Less suited to:
- 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 8x16 area at 2 inches takes about 1.0 tons.
- Weight used here: about 1.3 tons per cubic yard.
Where estimates go wrong
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
