Recycled Asphalt Millings: Costs, Pros, Cons and Best Uses

Recycled asphalt millings are old pavement that has been ground up and reused as a driveway surface, a road base or a fill. They cost far less than new asphalt, and they pack down into a firm, dark surface when you install them properly. They also vary from load to load, they soften in hard heat, and they are not the same as a paved driveway. This guide covers what you are buying, what it costs, how millings compare with gravel and limestone, and how to install them so they last in South Texas.

TL;DR

• Millings are ground-up pavement still coated in asphalt binder. One 2026 cost guide puts them at roughly $7 to $25 per ton, against $80 to $150 for new asphalt. Delivery often decides the final number.
• They beat plain gravel for staying in place and shedding dust, but they are rougher and less uniform than a paved surface.
• Results depend on compaction. Spread in thin lifts on a prepared base and compact each one.
• For heavy loads, blend millings with virgin aggregate or use crushed limestone road base instead.
• We deliver screened millings across the San Antonio area. Ask for a per-load quote before you order.

What recycled asphalt millings are

Millings come from milling machines that grind the top layer off a road before it is resurfaced. That material is a close relative of reclaimed asphalt pavement (RAP), a broader term that also covers asphalt pulled up from subbases and other paved surfaces.

In practice the two names get used for the same pile. What matters to a buyer is the same in both cases: the stone pieces are still coated in asphalt cement. The FHWA notes that milled RAP can be processed to a desired gradation, so a supplier can screen it into a finer, more uniform product or leave it coarser.

That coating is why millings behave differently from gravel. In warm weather the binder softens slightly and helps the pieces knit together under compaction. Over a season, the surface firms up into a semi-bound layer.

What recycled asphalt millings cost

A 2026 cost guide reports that millings often run $7 to $25 per ton, while new hot-mix asphalt runs $80 to $150 per ton. Treat those as a range, not a quote. Prices move with how much resurfacing is happening nearby and how far the truck has to go.

The FHWA breaks down a delivered recycled-material price into the raw material, processing, stockpiling, loading, hauling and profit, and says transportation can be a significant or even determining part of the total. That matches what we see on the road. A cheap ton from a yard across the county can cost more delivered than a slightly pricier ton from one close to your site.

The FHWA also says costs vary by location and construction time, so use local contractor information rather than a national average. For a firm number on your address, our asphalt millings page is where to start a quote request.

How much you need

Most residential jobs are priced by the ton but planned by volume. A rough way to plan:

1. Measure length and width of the area in feet.
2. Pick a compacted depth. Driveways commonly use 3 to 4 inches of millings over a prepared base.
3. Multiply length by width by depth in feet to get cubic feet, divide by 27 for cubic yards.
4. Add 10 to 15 percent, because loose material compacts down.
5. Ask your supplier for the weight per cubic yard of the actual product, since screened and unscreened millings differ, and convert to tons.

Pros and cons of recycled asphalt millings

Pros

• Lower cost. The savings against new pavement are large, and the same guide cites 50 to 75 percent less than new asphalt.
• A self-binding surface. With compaction and some warm weather, the binder helps the surface harden over time.
• Drainage. An unsealed millings surface lets water move through it, and compacted millings shed more than they absorb.
• Reuse. The FHWA says reusing RAP makes economic, environmental and engineering sense by conserving natural resources, reducing landfill disposal and lowering transportation costs.
• Simple equipment. Spreading and compacting millings uses standard compaction equipment, not heated paving machinery, which is why many owners treat it as a more DIY-friendly job.

Cons

• Inconsistent loads. Millings come from whatever road was milled that week. The FHWA advises that RAP from different sources should be sampled and tested to find the right blend for the job. Screened product reduces the surprise.
• Rutting and erosion if skipped steps. Researchers at the Recycled Materials Resource Center note RAP is susceptible to rutting if not properly engineered.
• Rougher look. It will not look like fresh black pavement. Expect a textured, dark gray to black surface with visible stone.
• Heat and tracking. In extreme heat the surface can soften and stick to tires and shoes. San Antonio summers make that a real consideration for a driveway in full sun.
• Sealcoating is uneven. Because of varying aged binder and exposed aggregate, millings do not always accept sealcoat evenly. Get it evaluated before you pay for treatment.
• Shorter life than new paving. One paving contractor suggests that for owners planning to stay in a home for the long term, traditional asphalt may be the better investment because millings need more maintenance.

Asphalt millings vs gravel for a driveway

This is the comparison most owners are really making. Here is how the two stack up on the points that decide a driveway.

Gravel is the better choice when you want a light, clean look, when the surface will be in full sun with a lot of foot traffic, or when you want decorative stone. Millings win when you want a firm, quiet, dark surface that stays put and costs less than paving. If your goal is water infiltration for a large area, our guide on permeable driveway materials and reservoir rules explains what to look for, because bound millings drain less freely than clean open-graded stone.

If you land on gravel, we deliver it too: see our bulk gravel delivery page.

Crushed asphalt vs limestone road base

A second common choice is crushed limestone road base, which is what many San Antonio driveways and pads sit on. The two are not interchangeable.

Crushed aggregates give more stability than rounded gravel because fractured faces interlock, and well-processed RAP shares that trait. But the FHWA also warns that RAP may have lower bearing capacity than conventional aggregates, so high-load uses call for a blend with virgin material.

In practice:

• Choose millings for a residential driveway, a farm or ranch road, a parking apron or a light-duty lot where cost and a firm, dust-free top matter most.
• Choose limestone road base for a structural base under concrete, for pads that carry heavy equipment, and for any spot where you need consistent, tested material.
• Use both in layers: limestone base underneath, millings as a wearing surface on top. Many owners get the best result and cost this way.

Our guide to road base for driveways covers the limestone side in more detail.

Can you use millings as fill?

Sometimes. The FHWA lists engineered fill, trench backfill, pipe bedding and culvert backfill as uses for RAP, with load-bearing uses usually requiring blending with conventional aggregate.

There are limits:

• A 2006 University of Texas study found RAP had adequate strength and hydraulic conductivity but significant creep and corrosion potential, and did not recommend it as backfill behind mechanically stabilized earth walls.
• A New Zealand transport guideline recommends placing millings above the water table with drainage measures and sealing the surface to limit stormwater exposure.
• If a building pad needs engineered support, use a fill specified for it, not whatever is cheapest. Our select fill is mixed for building pads, and the fill dirt calculator guide helps with quantities.

For structural work, check with your engineer or the plans. Do not substitute millings for specified fill.

How to install millings so they last

Most complaints about millings trace back to installation, not the material. The steps below follow the same logic as our guides on driveway base preparation and compacting road base.

1. Strip and shape. Remove topsoil, roots and soft spots. Grade so water runs off, not toward the house. Clay soils around San Antonio swell and shrink, so drainage matters.
2. Add a base where needed. On soft ground, put down crushed limestone base first. Our mud stabilization rock guide covers the rock sizes for wet areas.
3. Spread in thin lifts. Place millings in layers rather than one thick pile.
4. Compact every lift. RAP blends may compact well with little or no water using conventional equipment. A plate compactor works for small areas, and a roller for long drives.
5. Crown the surface. A slight crown or one-way slope sheds rain.
6. Let it set. A few warm days and some traffic help the binder lock the surface.
7. Maintain. Fill low spots early and re-compact before they turn into ruts.

One caution: if you plan to seal the surface, test a small area first. As noted above, millings can take sealer unevenly.

What we think about millings

We haul a lot of material around Bexar County and the surrounding cities, and millings come up often because of price. Our view is simple. Millings are a good product when the job fits them: a ranch road, a rural driveway, a parking area, a lay-down yard. They are a poor fit where someone expects a smooth paved look, or where heavy equipment will sit on a thin layer over soft clay.

We screen our millings so loads are more consistent, and we tell customers plainly when limestone road base is the better answer. If you tell us the use, the soil and the traffic, we will recommend the material and tonnage, and that sometimes means a cheaper order than you expected. Our trucks are GPS-tracked, we dispatch same-day or next-day when we can, and you talk to the owner, not a call center.

One more point for contractors: reuse also lowers what goes to landfill. If you are interested in the bigger picture, the benefits of reducing construction waste are worth reading alongside your material choices.

FAQ

What is the difference between asphalt millings and recycled asphalt?

Millings are the material ground off a road surface. Recycled asphalt, or RAP, is the wider category, which also includes asphalt removed from subbases and other paved surfaces. In everyday buying the terms often describe the same product, so ask the supplier for the gradation and whether it is screened.

What are the downsides of asphalt millings?

The main ones are load-to-load variation, rutting or erosion when they are not compacted, a rougher look than new pavement, and softening in extreme heat. Sealcoating can also go on unevenly. Most of these are reduced by buying screened product and compacting in lifts.

How much does a ton of recycled asphalt cost?

A 2026 guide puts millings at about $7 to $25 per ton before delivery effects are fully counted. Hauling distance can change the final cost a lot, so a delivered quote for your address is the number that counts.

Can you use millings as fill?

For trench backfill, pipe bedding and some engineered fills, yes, and load-bearing uses usually need blending with standard aggregate. They are not recommended behind MSE walls, and a building pad should get the fill your engineer specifies.
