How much crushed asphalt do I need?
What will my delivery cover?
Use this when a load has already arrived and you want to know how far it will go.
Convert cubic yards and tons
At 110 lb/ft³, one cubic yard is about 1.485 tons.
How to use the crushed asphalt calculator
A good estimate saves you a second truck trip and a second delivery fee. Here is the quick way through the tool:
- Pick a calculation mode. Open the Tonnage and Cost tab to get your order, the Coverage tab to see what a delivery will cover, or the Yards and Tons tab to convert between the two units.
- Enter the area. Type the length and width in feet, or switch to square feet mode and enter the total area if you already measured it.
- Set the compacted depth. Use the finished depth after compaction. Four inches suits most driveways, three inches suits parking pads, and two inches suits a resurface over firm ground.
- Check density and allowance. Leave density at 110 lb/ft³ unless your supplier says otherwise. Keep the 10% compaction allowance so the surface doesn’t end up thin.
- Calculate and copy. Press Calculate to see the order weight, truck loads, and material cost, then use Copy Results to send the numbers to your hauler.
Asphalt millings calculator: millings, crushed asphalt, and gravel
People use “millings” and “crushed asphalt” for the same thing most of the time, and the calculator treats them alike. There is a small difference. Millings come straight off a milling machine as fine, irregular pieces with old binder still on them. Crushed asphalt has gone through a crusher and a screen, so the pieces are more uniform. Both pack down to a similar weight, which is why one recycled asphalt calculator covers both.
| Compare | Millings | Crushed asphalt | Gravel |
|---|---|---|---|
| What it is | Milled old pavement | Crushed and screened millings | Natural stone |
| Binder | Leftover asphalt | Leftover asphalt | None |
| Dust | Low once rolled | Low once rolled | Higher on slopes |
| Best for | Driveways, lanes, pads | Driveways, base layers | Bases, drainage |

The leftover binder is what sets millings apart. In warm weather it softens a little and then sets as traffic and a roller press the surface down, which is why a millings driveway feels firmer than loose stone. If you are weighing it against a paved surface, compare the numbers in the asphalt driveway cost calculator.
How the crushed asphalt calculator works out tons
New hot mix weighs up to about 148 lb/ft³ once compacted, as the Federal Highway Administration’s recycled asphalt guidance describes. Millings laid as a driveway surface are looser, and 110 lb/ft³ is a sound planning figure once they’re rolled. The density menu lets you move that figure up or down by 10 pounds if your supplier tells you to.
With 110 lb/ft³ you can shorten it to one line:
If you have a square footage already, you can skip ahead to the numbers. If not, our free asphalt calculator square feet page helps you size an area and compare it with new asphalt.
Worked examples
These are the same sums the crushed asphalt calculator does for you, written out so you can check them.
Example 1: a 60 by 12 ft driveway at 4 inches
Area = 720 sq ft. Volume = 720 × 4 ÷ 12 = 240 cu ft, or 8.89 cu yd. Weight = 240 × 110 ÷ 2,000 = 13.2 tons. With a 10% allowance that’s 14.52 tons, so order 15 tons, which is one tri-axle load.
Example 2: a 20 by 20 ft parking pad at 3 inches
Area = 400 sq ft. Volume = 400 × 3 ÷ 12 = 100 cu ft (3.70 cu yd). Weight = 100 × 110 ÷ 2,000 = 5.5 tons. With 10% extra that’s 6.05 tons, so order 6.5 tons and leave a little for the edges to spread.
Example 3: a 400 by 12 ft farm lane at 4 inches
Area = 4,800 sq ft. Volume = 4,800 × 4 ÷ 12 = 1,600 cu ft (59.26 cu yd). Weight = 1,600 × 110 ÷ 2,000 = 88 tons. With 10% extra that’s 96.8 tons, so order 97 tons, about 6.5 loads of 15 tons. At $20 per ton the material is roughly $1,940.
How thick should crushed asphalt be?
Depth is where most people go wrong. Too thin and the surface ruts and breaks up. Too thick and you pay for tons you don’t need. These are the depths that usually work, with what each takes per 1,000 square feet. Type your chosen depth into the crushed asphalt calculator above to size the whole job:
| Use | Depth | Cu yd per 1,000 sq ft | Tons per 1,000 sq ft |
|---|---|---|---|
| Walkway or path | 2 in | 6.17 | 9.17 |
| Parking pad, light cars | 3 in | 9.26 | 13.75 |
| Residential driveway | 4 in | 12.35 | 18.33 |
| RV pad or farm road | 6 in | 18.52 | 27.50 |
Swipe the table sideways to see all columns.
On soft or wet ground, put a layer of compacted stone under the millings first. The pavement calculator helps you plan the layers. Anything thicker than about 4 inches is best placed in two lifts, rolling each one before you add the next.
Crushed asphalt coverage per ton
This works like a crushed asphalt coverage calculator in table form. It shows how far one ton goes at each finished depth, using 110 lb/ft³.
| Compacted depth | Coverage per ton | Typical use |
|---|---|---|
| 2 in | 109 sq ft | Resurfacing firm gravel |
| 3 in | 73 sq ft | Parking pads, light lanes |
| 4 in | 55 sq ft | Residential driveways |
| 6 in | 36 sq ft | RV pads, farm roads |
Swipe the table sideways to see all columns.
A 15-ton load covers about 820 sq ft at 4 inches and about 1,640 sq ft at 2 inches.
Laying a millings driveway, step by step
- Prepare the ground. Strip sod and soft soil, then grade the area so water runs off. Fix soft spots first, because millings won’t hide them.
- Add a base where needed. Soft or clay-heavy ground needs a few inches of compacted stone underneath.
- Spread the millings. Spread to a slightly higher depth than you want, since it will settle. Crown the middle of the drive by about a quarter inch per foot so rain sheds off.
- Compact it. Use a vibratory roller or a heavy plate compactor and make several passes. Doing this on a warm day helps the binder set.
- Roll again after a few days. A second pass after traffic and sun have worked on it firms up the surface.
The mistakes that cause most callbacks are skipping the compaction, laying it over a wet base, and ordering exactly the calculated tons with no allowance. The compaction allowance in the crushed asphalt calculator exists for that last one.
What does crushed asphalt cost?
Millings are cheap compared with new paving, which is the main reason people choose them. Prices swing by region and by how far the truck has to go. Run your size through the crushed asphalt calculator first, then use the numbers below as a planning range. They draw on Angi’s asphalt millings cost guide and local supplier ranges, and your own quote may differ.
| Item | Rate | Estimate |
|---|---|---|
| Millings, 15 tons | $10–$35 per ton | $150–$525 |
| Delivery, one load | $30–$100 per load | $30–$100 |
| Material and delivery | $180–$625 | |
| Contractor installed, 720 sq ft | $3–$8 per sq ft | $2,160–$5,760 |
Swipe the table sideways to see all columns.
Contractor prices include grading, spreading, and compaction, and they vary a lot with access and ground conditions. Delivered material is often the cheapest way to cover a large area.

Frequently asked questions
How does this crushed asphalt calculator work out tonnage?
It multiplies your area by the compacted depth to get volume, applies a density of 110 lb/ft³ (you can change it), and divides by 2,000 to get short tons. Then it adds your compaction allowance and rounds the order up to the nearest half ton.Are asphalt millings good for a driveway?
Often, yes. Millings contain leftover asphalt binder that softens in summer heat and sets as traffic and a roller press it down, so they tend to bind better and kick up less dust than loose gravel. They still need a firm base and good drainage, and they won’t match the life of a new hot mix surface.How much is a load of asphalt millings?
Millings usually sell for about $10 to $35 per ton depending on your area and the supplier. A 15-ton load therefore runs roughly $150 to $525 for the material, and delivery often adds $30 to $100.How much is 20 tons of asphalt millings?
At $10 to $35 per ton, 20 tons costs about $200 to $700 for the material before delivery.How much does one dump truck load of crushed asphalt cover?
A 15-ton tri-axle load covers about 820 square feet at 4 inches compacted, or about 1,640 square feet at 2 inches.Does crushed asphalt need to be compacted with a roller?
Yes. Rolling (or a heavy plate compactor on small areas) locks the pieces together and lets the binder set. Without it the surface stays loose, ruts under tires, and sheds material.How do I use the crushed asphalt calculator with square feet?
Multiply length by average width to get square feet, then choose the square feet option in the calculator and type that number in. If the area is an odd shape, split it into rectangles and add them up.How much does a cubic yard of crushed asphalt weigh?
At a compacted 110 lb/ft³, one cubic yard weighs about 2,970 lbs, or roughly 1.485 tons.Is recycled asphalt as durable as regular gravel?
On a well-prepared base, it is often more stable than loose gravel because the binder helps it bond, and it tends to wash out less in heavy rain. Durability still depends on drainage, depth, and compaction.How many tons of millings do I need for a 60 by 12 foot driveway?
At 4 inches compacted that is 720 square feet, 8.9 cubic yards, and 13.2 tons. With a 10% allowance you would order about 15 tons, which is one tri-axle load.Sources and resources
