How this was calculated
Formula source(s)
- Inverse of approximately 1.6 short tons per cubic yard
- 1 short ton = 2,000 lb; a metric tonne is about 10% heavier
Inputs used
- Asphalt Millings weight (short tons)
- 10
Intermediate steps
- Conversion factor applied
- 0.63 yd³ per short ton
Confidence note: About 1.6 short tons per cubic yard for loose asphalt millings; compacted millings are considerably denser. Loose material occupies more space than stacked or compacted material.
What this calculation does not cover
- Unscreened planings come with bound lumps well above the size of any aggregate in the mix that was cut, which is why millings bought for reuse are usually screened or crushed first. A layer only a particle or two deep cannot lock together and ravels under wheels. Take the area down rather than the depth.
- Some of the tonnage never becomes depth. On a rutted or soft base the millings key into the low spots before thickness starts building, usually the larger of the two losses; at an unrestrained edge the roller has nothing to compact against, so the perimeter stays loose and sheds under traffic. Grade the base and edge the run rather than stacking two more allowances on the consolidation one.
- Traffic finishes whatever compaction the roller did not. Left to it, the wheel paths consolidate and the rest does not, so within weeks the run carries two firm tracks with looser material between and beside them. That is a rolling failure rather than a shortfall in tonnage, and the answer is passes across the full width, not more material.

Converting a millings tonnage to volume is how you check whether a load will surface the area you have. The behaviour that distinguishes millings from ordinary aggregate is that they partially re-bind: the old bitumen still present softens in the sun and, under compaction, knits the surface together into something firmer than loose stone. That means a millings surface laid in cold weather stays loose and one laid in heat sets up well, which affects both how much material beds down and how the finished surface performs.
