Tons of Asphalt Millings per Mile of 28 ft Road
Tons of asphalt millings per mile of 28 foot road: about 2,373 tons at 4 inches deep. The strip is 28 ft × 5,280 ft = 147,840 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 | 1,780 | 128 |
| 4 in | 2,373 | 170 |
| 6 in | 3,559 | 255 |
| 8 in | 4,745 | 339 |
The math
- Area: 28 × 5,280 = 147,840 sq ft.
- Volume at 4 in: 147,840 × 0.333 = 49,280 cu ft (1,825 cubic yards).
- × 1.3 tons per yard = 2,373 tons.
Building a road this width
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.

When to choose 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
Poor fit 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 10x20 area at 3 inches takes about 2.4 tons.
- Weight used here: about 1.3 tons per cubic yard.
Common estimating mistakes
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
