If you’re planning a driveway, parking area, or rural road project, an asphalt millings calculator is one of the most useful tools you can have at your fingertips. Asphalt millings—also known as crushed asphalt or recycled pavement—are a cost-effective and eco-friendly alternative to new asphalt, but estimating how much material you’ll need can be tricky without the right math.
This calculator takes the guesswork out of your project by helping you determine the amount of asphalt millings required based on your project’s dimensions, desired depth, and material density. Whether you’re a homeowner tackling a weekend project or a contractor working on a larger job, this tool ensures you can plan with precision and avoid costly over- or under-ordering.
What Are Asphalt Millings?
Asphalt millings are the recycled remnants of old asphalt pavement that’s been ground up during resurfacing or demolition projects. These particles retain much of the binding properties of traditional asphalt, making them an effective, low-cost alternative to hot mix asphalt. Unlike gravel, millings naturally bond together over time, especially when compacted and exposed to sun and moisture.
Common Uses for Asphalt Millings
Asphalt millings are widely used in both residential and commercial projects. Their most common applications include:
- Driveways
- Private roads and farm lanes
- Parking pads and turnarounds
- Walkways and pathways
- Base layers for new asphalt paving
These versatile materials are especially popular for rural or budget-conscious projects, where full asphalt paving may not be necessary.
How to Use the Asphalt Millings Calculator
Estimating how much recycled asphalt you need can be overwhelming without the right tool—especially when you’re working with uneven terrain or variable project depths. That’s where our asphalt millings calculator comes in. It simplifies your planning process by providing an accurate material estimate in just a few clicks.
Step-by-Step Instructions
- Measure Your Project Area
Start by measuring the length and width of the area you plan to cover in feet. If the space isn’t a perfect rectangle, break it into smaller sections and calculate each one separately. - Decide on Depth
Input the desired depth in inches. Most driveways or parking areas use 3–4 inches of millings, but deeper layers may be needed for heavy-use surfaces. - Enter Material Weight (Density)
The calculator defaults to 110 lbs per cubic foot, which is the average density of asphalt millings. If you have supplier-specific data, you can update this value. - Optional: Add Cost Per Ton
If you know the current price per ton of asphalt millings in your area, enter it to estimate your total material cost. - Optional: Add Compaction Percentage
Because millings compact after installation, it’s wise to add extra to your estimate. The default is 15%, but you can adjust this depending on your project. - Click Calculate
The tool will instantly provide an estimate in tons and, if applicable, cost.
Example Calculation
Let’s say you’re resurfacing a 50 ft × 12 ft driveway with 4 inches of depth. Using the default density and 15% compaction:
- You’ll need about 11 tons of asphalt millings
- If they cost $25 per ton, your estimated material cost would be $275
Understanding the Asphalt Millings Formula
To provide accurate estimates, our asphalt millings calculator uses a simple formula based on the volume of the area and the material’s density. Here’s how it works:
Tons = (Length × Width × (Depth in inches ÷ 12) × Density in lbs/ft³) ÷ 2000
What Each Part Means:
- Length × Width: Gives you the surface area in square feet.
- Depth in inches ÷ 12: Converts depth into feet for volume calculation.
- Density in lbs/ft³: Asphalt millings typically weigh about 110 pounds per cubic foot, but this can vary based on moisture, composition, and compaction.
- Divide by 2000: Converts pounds to tons, which is how materials are sold and delivered.
Should You Add Extra for Compaction?
When working with asphalt millings, one important factor to consider is compaction. Unlike gravel, which stays relatively loose, millings bind and compress under pressure—especially with the help of sun, moisture, and mechanical compaction.
What Is Compaction?
Compaction refers to the process of pressing down the millings after they’re laid, reducing air gaps and binding the particles together. This creates a denser, more solid surface over time. However, this also means the material settles and takes up less volume than when it was loose.
Why Add 15% to Your Estimate?
To account for this shrinkage, it’s common practice to add an extra 10–20% to your asphalt millings estimate. Our calculator defaults to a 15% compaction adjustment, which is a balanced choice for most residential and light commercial projects.
This ensures:
- You won’t run short on material halfway through
- Your final surface meets your desired depth and coverage
- You avoid multiple delivery fees or sourcing problems
Customize It Based on Your Needs
Some factors may affect how much you should add:
- Type of compactor used (plate compactor vs. roller)
- Weather conditions during installation
- Moisture content in the millings
- Desired surface firmness (for light foot traffic vs. vehicle load)
That’s why our calculator lets you enter your own compaction percentage—so you can plan more precisely for your unique conditions.
How Much Do Asphalt Millings Cost?
One of the main reasons people choose asphalt millings over fresh asphalt or concrete is cost savings. But like any construction material, the price per ton of asphalt millings can vary depending on a few key factors.
Typical Price Range
On average, asphalt millings cost between $10 and $30 per ton, though prices can go higher depending on location and availability. Here’s a breakdown of common price ranges:
- Low-end (bulk recycled material): $10–$15 per ton
- Mid-range (screened or semi-processed): $15–$25 per ton
- High-end (processed and graded): $25–$40+ per ton
Keep in mind that some suppliers may also charge delivery fees, especially if you’re ordering small quantities or are located far from the recycling site.
What Affects the Cost of Asphalt Millings?
Several variables influence the final price you’ll pay:
- Your location – Prices can be higher in urban or remote areas
- Supply and demand – Limited availability can drive prices up
- Processing level – Clean, screened, or blended millings cost more
- Delivery distance – The farther it has to travel, the more it costs
- Quantity ordered – Larger bulk orders often get lower per-ton pricing
Use the Calculator to Estimate Cost
If you know the cost per ton in your area, you can enter it directly into the asphalt millings calculator. Once you input your dimensions and compaction rate, the calculator will estimate the total material cost based on your tonnage.
For example:
- 12 tons × $25/ton = $300 total
This helps you plan your budget ahead of time and compare pricing from different suppliers.

FAQs
What is the density of asphalt millings?
The average density of asphalt millings is approximately 110 pounds per cubic foot (lbs/ft³). This value represents how much the material weighs per unit of volume and is crucial when calculating how many tons you'll need for a project.
However, the actual density can vary depending on several factors:
-
Moisture content — Wet millings are heavier than dry ones
-
Particle size and uniformity — Finer, compacted millings may weigh more
-
Binder content — Higher asphalt content increases density
-
Compaction — Compressed millings weigh more per cubic foot
If you’re purchasing from a specific supplier, it’s always best to ask for the material specs. Our asphalt millings calculator uses 110 lbs/ft³ as the default but lets you enter your own value for greater accuracy.
How to Harden Asphalt Millings
To harden asphalt millings and create a solid, long-lasting surface, follow these proven steps:
-
Grade and Level the Surface
Start with a clean, even base. Use a landscape rake or grader to level the area where you’ll install the millings. A slight crown helps with water runoff. -
Lay the Asphalt Millings
Spread the recycled asphalt evenly over the surface. A depth of 3–4 inches is common for driveways and light traffic areas. -
Wet the Surface
Lightly spray the millings with water to help activate the binding agents in the recycled asphalt. Don’t soak it—just dampen the material. -
Compact the Millings
Use a vibratory plate compactor or a drum roller to compact the surface thoroughly. Start from the center and work your way out. Compacting helps the particles interlock and bond together. -
Allow Time to Cure
Let the surface cure for a few days. Exposure to sun and warm temperatures helps further bind the material, improving hardness over time. -
Optional: Apply a Binder or Sealant
For extra durability, some homeowners apply a commercial-grade asphalt binder or emulsion to the surface. This helps lock the particles in place and reduces dust.
