Asphalt Millings Tons to Cubic Yards Calculator

Convert a asphalt millings tonnage into cubic yards to check capacity, coverage and storage.

Approximate volume

6.25 cu yd

High confidence

About 1.6 short tons per cubic yard for loose asphalt millings; compacted millings are considerably denser. The inverse of the volume-to-weight figure. Loose material occupies more space than stacked or compacted material.

Conversion factor applied
0.63 cu yd per short tons

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.

Add the equipment this sizes

This result is a specification — 6.25 cu yd — not a quantity. Put the thing it sizes into your project: how many, what you call it, and your supplier’s price.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.

Frequently asked questions

How much area will this tonnage cover?
Convert to volume and divide by the area for a loose depth, then reduce for compaction. Millings consolidate appreciably, so the finished depth is meaningfully less than the spread depth.
Do millings need a binder?
Not necessarily — the residual bitumen provides some binding under compaction and warmth. Where a firmer surface is wanted, a bituminous emulsion can be applied, which moves the cost closer to conventional surfacing.
Are millings environmentally preferable?
Reusing them avoids both landfill and new material production, which is a genuine benefit. They are among the most recycled construction materials, and using them locally avoids haulage as well.
