What this guide covers
Millings get quoted a lot on long rural driveways, farm roads and yards where getting in and out in rain and snow matters more than looks. This guide covers what recycled asphalt pavement is, what it costs, where it holds up, and the failures I see most.
If you are a contractor, the section on what a quote should spell out is the part to use. If you are comparing materials, start with the comparison table. For how contractors use the same material inside new hot mix, see RAP asphalt.

What is recycled asphalt pavement?
Recycled asphalt pavement, or RAP, is removed or reprocessed pavement material containing asphalt and aggregates. It is typically 3 to 7 percent asphalt by weight, and processed RAP is usually crushed or milled to 1.5 inches or less.
The same material is sold as asphalt millings, grindings or reclaimed asphalt pavement, depending on who is selling it. Most of it goes back into new asphalt. About 89% of RAP is reused in new mixtures and about 11% goes to other uses such as unbound aggregate bases, and new mixes average 21.9% RAP. Millings sold for driveways fall in that second group.
The glossary entry for recycled asphalt has the short definition.
Are asphalt millings good for a driveway?
Asphalt millings work as a low-cost driveway surface on a sound, well-drained base when they are spread thick enough and rolled. They stay a firm aggregate surface rather than a sealed pavement, which puts them between gravel and new hot mix.
Where millings make sense
In my experience, millings are most often used on long rural driveways, where looks matter less than being able to get in and out in rain and snow. They are a utility surface. There is no way they are going to look that great, and the mat will be much rougher than new asphalt.
The biggest thing to know is that the material is different on every load, because it depends on the asphalt that was milled out. If the old pavement was so far gone that it had nearly turned to gravel, you receive something close to gravel. If it came up in large chunks, or as clean, finely milled asphalt, you get a different product again. All of that ends up in your driveway.
There is real long-term use behind the idea. Douglas County, Nevada, has surfaced low-volume roads with RAP millings for more than two decades, designing them from field experience, according to a 2018 University of Nevada, Reno thesis written to give those roads design guidelines.
Why the base matters more than the millings
FHWA reports that RAP on its own may have lower bearing capacity than conventional granular base. It lists California Bearing Ratio values of 20 to 25 percent for 100 percent RAP, against 150 percent or higher for a blend of 40 percent RAP and 60 percent natural aggregate. Those figures are for use as an unbound base, but they point the same way for a driveway: soft or wet ground is where millings alone struggle.
I have not found an agency standard for residential millings driveways, so the thickness numbers you see online come from suppliers and they disagree. Ask the supplier what compacted depth they recommend for your subgrade and traffic, and get it in writing.
How much do asphalt millings cost?
Angi's September 2026 cost guide puts installed asphalt millings at $3 to $8 per square foot, with most homeowner projects between $7,875 and $22,625. Treat those as national averages, because the price on your property depends on things the average hides.
What moves the price
- Material price per ton. Some plants and recycling yards sell millings and some only take old asphalt in, so the price, and whether there is one, varies plant to plant.
- Distance. Trucking from the nearest source is billed on top of the material.
- Site preparation. Grading, drainage and any base added under the millings.
- Thickness and area. These set the tonnage. The asphalt tonnage calculator turns area and thickness into tons, and the driveway cost calculator adds the installed cost.
- Compaction. The material needs rolling, so access for a roller affects who can do the work.
What I see in the Bay Area
In the San Francisco Bay Area, as of October 2026, I see millings at about $10 to $20 per ton, while hot mix asphalt can run anywhere from about $78 to $130 per ton depending on where you are buying it. That compares material prices only. It is not a quote for a job, and it will be different in your market and from plant to plant.
We do not publish a reported millings price per ton yet because we do not have enough dated reports, so the range above is my own, not a quote. If you bought a load recently, report the price so it can be checked and shown with its date. For the wider cost picture, see the asphalt paving cost guide and the driveway replacement cost guide.
How do millings compare with gravel and new asphalt?
Millings are sold as a low-cost surface and hold together better than loose gravel, but they are not a sealed surface. New hot mix is the only one of the three that is rolled into a sealed pavement.
| Surface | What it is | How it behaves | What it needs |
|---|---|---|---|
| Asphalt millings | Old asphalt ground off a road and reused as it is | Packs down firm when rolled, does not seal like new hot mix | A sound, well-drained base and compaction |
| Gravel | Crushed stone with no binder | Stays loose under traffic | Periodic topping and regrading |
| New hot mix | Heated aggregate and asphalt binder, placed hot | Rolled into a sealed surface | A prepared base and a paving crew |

What goes wrong with a recycled asphalt driveway?
Beyond the rougher surface and the load-to-load inconsistency, these are the failures I see most:
- Junk in the load. Millings are often unscreened and can have chunks of concrete, vegetation, nails, rebar and more in them, which can flatten tires.
- Ruts and potholes. Millings are much more likely to rut and pothole than new asphalt.
- Washouts when the rainy weather comes.
- Edges that crumble pretty quickly.
- Shedding and tracking, where loose stones come out and get carried off.
- Softening in extreme heat, which leads to sinking.
The biggest problem is often not the RAP itself. It is that the base and subbase were not prepared correctly before the millings went on, usually because the owner chose millings to save money and is not going to spend much on the base. Because RAP alone has lower bearing capacity than conventional base and millings are loose until rolled, a driveway on soft ground, with water running across it, or rolled too little is the one that ruts and sheds.
What should a millings quote spell out?
A millings quote should say what you are getting and how it goes down, because every item below is a place these jobs go wrong. If a quote says only "millings, driveway, one price," ask for the rest before you sign.
- The compacted thickness, not just the loose depth.
- What is under the millings: grading, drainage and any base material.
- Whether the millings are screened or unscreened, and to what size.
- Where the material comes from, since it changes load to load.
- How it will be compacted and with what equipment.
- What is not included, such as edges, sealing or fixing drainage.
Where can you buy recycled asphalt millings?
Asphalt plants and recycling yards are the usual sources. Some plants sell millings, some only take old asphalt in, and it varies plant to plant, and a plant's page in the directory says so where we have asked. Use the asphalt plant finder to see what is within reach.
Ask these before you order:
- Do you sell millings, and do you take old asphalt in?
- Are they screened or unscreened, and what size?
- Is the price per ton or per load, and is loading or delivery included?
- What is the minimum order, and what are the loadout hours?
Frequently asked questions
Will a millings driveway hold up in rain and snow?
They work as a low-cost surface on a sound, well-drained base when they are spread thick enough and rolled. They are rougher than new asphalt, they vary from load to load, and they fail quickly on a poorly prepared base.
How much does a ton of asphalt millings cost?
Angi's September 2026 guide puts installed millings at $3 to $8 per square foot. In the San Francisco Bay Area, as of October 2026, the material itself runs about $10 to $20 per ton. Your price depends on distance, base preparation and who installs it.
How long does a recycled asphalt driveway last?
Supplier guides commonly quote 20 to 30 years, such as Rolling Wedge's millings driveway guide, but Rolling Wedge sells milling equipment and I have not found an independent study of residential driveways. Treat that range as a best case that assumes a good base and proper compaction.
Can you use asphalt millings for a parking lot?
For loaded traffic, FHWA's lower bearing figures for RAP on its own are the reason to ask for an engineered base first. For any route that has to be accessible, the ADA Standards require that floor and ground surfaces be stable, firm and slip resistant, and loose millings may not meet that. Local code varies, so confirm with the authority that approves the lot.
Is it safe to put millings near a creek or drainage?
Rules vary by county and state, so check with your county before placing them near water. A review for the National Asphalt Pavement Association found extensive knowledge gaps about what is in RAP, how mobile it is and how toxic, and Florida has funded further research on leaching.
Do I need a contractor to install millings?
Spreading and rolling millings is equipment work, and the crews that do it are usually paving or grading firms. If you would rather hire it out, get written proposals that state the compacted thickness and the base preparation.
Before you hire: This article gives general materials and estimating information, not engineering, legal or code advice. Prices shown are one person's observation in one market and are not quotes. Millings quality, local rules on placing recycled asphalt, and ADA surface requirements vary by source and jurisdiction, so confirm them with your supplier, contractor and local authority.
