How many tons is a cubic yard of asphalt?

1.96 US tons compacted — 27 ft³ × 145 lb/ft³ = 3,915 lb. Rounding to 2 tons per yard overstates the order by about 2%, which is usually harmless and often useful as built-in waste. Loose material in the truck is only about 1.58 tons per cubic yard.

How many cubic yards is a ton of asphalt?

0.51 compacted cubic yards — one ton divided by 1.96 tons/yd³. In coverage terms, a ton placed 3 inches thick compacted covers about 55 ft². Twenty tons, a typical tandem-plus load, therefore builds roughly 10.2 yd³ of finished mat.

Why do asphalt plants sell by the ton instead of by the yard?

Because weight is unambiguous. Volume changes with temperature, handling and compaction — the same ton occupies about 25% more space loose than rolled — but the scale ticket reads the same regardless. Plants batch by weight, trucks are weighed loaded and empty, and you pay for the difference.

Should I convert loose or compacted yards to tons?

Compacted, almost always. Your takeoff (area × thickness) describes the finished, rolled mat, so multiply by 1.96 tons/yd³. Only use the loose factor (~1.58 tons/yd³) when you are sizing truck volume or estimating a stockpile — never for ordering against plan dimensions.

How much extra should I add when converting a takeoff to an order?

5% covers handbook waste on straightforward geometry — handwork around structures, yield variation and cleanup. Irregular edges, many penetrations or thin variable-depth leveling courses justify 7–10%. Then round up to the plant's sale increment, typically the half ton or full ton.

Does the 1.96 factor change with mix type?

A little. It is built on 145 lb/ft³ dense-graded hot mix; cold mix compacts nearer 137 lb/ft³ (1.85 tons/yd³) and compacted millings about 122 lb/ft³ (1.65 tons/yd³). If the mix design sheet lists a different maximum density, derive the factor from that instead of the table value.

Tons vs cubic yards

You measure the job in cubic yards; the plant sells it in tons. One factor — 1.96 US tons per compacted cubic yard — links the two, and getting it backwards is the most expensive unit mistake in paving.

Two units, one material

A cubic yard is what your tape measure produces: area times compacted thickness. A ton is what the scale house produces: the truck weighed loaded minus its tare. Compacted dense-graded hot mix weighs 145 lb/ft³, so one cubic yard of finished mat is 27 × 145 = 3,915 lb — 1.96 US tons. Every conversion on this page is that single density restated.

The conversion, both directions

Formula

Tons = yd³ × 1.96

yd³: compacted volume from your takeoff (cubic yards)
1.96: US tons per compacted cubic yard (tons/yd³)

Use when ordering: volume in, weight out.

Formula

yd³ = tons ÷ 1.96

tons: weight from the scale ticket or quote (US tons)
1.96: US tons per compacted cubic yard (tons/yd³)

Use when checking coverage: weight in, compacted volume out.

Quick-convert table

Common takeoff volumes converted at 1.96 tons per compacted cubic yard, with the reverse check alongside.

Compacted dense-graded hot mix at 145 lb/ft³. Add waste before rounding to the plant's sale increment.
Compacted volume	Weight in US tons	Reverse: tons → yd³
1 yd³	1.96 tons (3,915 lb)	2 tons ≈ 1.02 yd³
5 yd³	9.8 tons	10 tons ≈ 5.1 yd³
10 yd³	19.6 tons	20 tons ≈ 10.2 yd³
20 yd³	39.2 tons	40 tons ≈ 20.4 yd³
50 yd³	98 tons	100 tons ≈ 51 yd³

Loose vs compacted yards

From takeoff to order

Worked example: 12 yd³ takeoff

A parking-area takeoff comes to 12 compacted cubic yards of dense-graded hot mix. The plant sells in whole tons.

1
Convert volume to weight
12 yd³ × 1.96 tons/yd³ = 23.5 tons
2
Add 5% waste for handwork and yield
23.5 × 1.05 = 24.7 tons
3
Round up to the sale increment
24.7 → 25 tons

Result: Order 25 US tons — one tri-axle plus one small tandem load, or two tandem loads.
