Driveway Planning
Recycled Asphalt Driveway vs New Asphalt: Which Is Right for You?
Quick answer: A recycled asphalt driveway is made from asphalt millings: old pavement that is ground up, spread and compacted. It costs less than new hot-mix asphalt and firms up better than gravel, but it stays rougher, can loosen if it is not compacted well, and needs more upkeep. Millings suit long rural lanes and budget projects, while new asphalt is worth it for a smooth, low-maintenance driveway that lasts.
Around Lindsay, Peterborough, Bobcaygeon and Fenelon Falls, a lot of driveways are long, rural or both, and paving the whole length in new asphalt is a big number. That is usually when homeowners start asking about a recycled asphalt driveway.
For the right driveway it is a good option, but it is a different surface from new asphalt, and the difference matters more than the name suggests. Here is how the two compare and how to decide.

What Is a Recycled Asphalt Driveway?
When a road or parking lot is resurfaced, the top of the old pavement is usually ground off with a milling machine. What comes off is called asphalt millings, or reclaimed asphalt pavement. It is crushed stone that is still coated in the old asphalt binder, typically a few percent of its weight.
A lot of that material goes straight back into new asphalt at the plant. Asphalt is one of the most recycled materials there is, which our guide to the environmental benefits of asphalt covers in more detail. Some of it is sold as a driveway material in its own right.
A recycled asphalt driveway, then, is a driveway surfaced with those millings. They are spread and graded like gravel, then compacted with a roller, and the old binder on each piece helps the material knit together into a firmer surface than loose gravel.
It is not re-heated or re-mixed with new binder the way hot-mix asphalt is at a plant, and that is where the differences come from.
Recycled Asphalt vs New Asphalt: The Main Differences
Both surfaces start from the same kind of material, but they are built differently and they behave differently.
| Recycled asphalt (millings) | New hot-mix asphalt | |
|---|---|---|
| What it is | Ground-up old asphalt, spread and compacted cold | Fresh asphalt mixed hot at a plant and paved |
| Surface | Rougher, textured, less uniform in colour | Smooth, even, uniform black |
| How it holds together | Compaction plus the old binder on the stone | Fresh binder, laid hot and rolled |
| Upfront cost | Lower | Higher |
| Upkeep | Top-ups, re-grading or re-compaction over time | Crack filling and periodic sealcoating |
| Best fit | Long lanes, rural driveways, parking pads, budget projects | Main driveways, curb appeal, low maintenance |
Cost. Millings are the cheaper option: the material has already been produced once, so it costs much less per ton than new asphalt, and putting it down is closer to installing gravel than to paving. The saving is only in the top layer, though: excavation, removing soft soil, grading for drainage and building a compacted base cost the same whichever surface goes on top.
Finish. Compacted millings do not become a smooth, sealed surface: the texture stays rough, and the colour varies with where the material came from. That is often fine on a long lane through the trees, but most people notice it on the driveway in front of the house.
Consistency. The quality of millings depends on the pavement they came from, so one load can be cleaner and better graded than another. New asphalt is produced to a mix design, so what arrives is much more predictable.
Staying put. If millings are not compacted properly, vehicle traffic can loosen the surface and leave it uneven. A good installer compacts in layers, and the surface may need re-compacting or topping up over time.
Where a Recycled Asphalt Driveway Makes Sense
Millings are a practical choice when function matters more than finish:
- Long rural driveways and cottage lanes. When a driveway runs a few hundred feet, the saving per foot adds up fast, and a firm, textured surface is often all the lane needs.
- Parking pads and side areas. Space for a trailer, a boat or an extra vehicle beside the main driveway.
- Upgrading from gravel. If your gravel driveway ruts, washes out or throws stone onto the lawn, compacted millings are firmer and tidier.
- A budget first stage. Some homeowners put down millings now and pave with new asphalt later, once the base has had time to settle and the budget allows.
Where New Asphalt Is Worth the Extra Cost
New hot-mix asphalt is the better choice when:
- It is the driveway in front of the house. A smooth, even, uniform surface is what most people want to look at every day.
- You want low maintenance. A properly built asphalt driveway needs crack filling and occasional sealcoating, not regular top-ups. Our guide to when to sealcoat your driveway covers the upkeep.
- Kids, bikes and basketball. Rough millings are not much fun to ride or play on.
- You plow or snow-blow a lot. A smooth, bound surface is easier to clear without catching or scraping it up.
- You want it to last. New asphalt on a proper base is the longer-lived surface, and it holds its shape under turning wheels.
If the budget is the only thing pushing you towards millings on your main driveway, it is worth getting a quote for both. The gap is often smaller than expected once the preparation, which is the same for both, is included. Our guide to what goes into driveway paving cost in Ontario explains what drives that number.
The Base Matters Just as Much for Millings
The most common mistake with a recycled asphalt driveway is treating it as a way to skip the groundwork. It is not. A millings surface on soft, wet or poorly compacted ground will rut and heave just like asphalt would, and Ontario’s freeze-thaw cycle does its damage from underneath whatever the surface is.
A millings driveway still needs:
- Excavation to a firm subgrade, with topsoil, roots and soft clay removed.
- Grading for drainage, so water runs off and away from the driveway rather than sitting under it.
- A compacted base of crushed stone, built up and compacted in layers.
- Millings compacted in layers, not dumped at full depth and rolled on top.
Millings are not a substitute for a proper base stone either. Research on reclaimed asphalt used as base material found that its bearing strength falls and compaction gets harder as the share of old asphalt increases. That is why a contractor will not usually build the whole base from millings under a paved driveway.
Our guide to asphalt driveway thickness explains how deep a good base needs to be and why it does most of the work.
What to Ask Before You Choose
Whichever surface you are leaning towards, these questions get a straight comparison:
- Where do the millings come from, and how are they processed? Cleaner, better-graded material performs better.
- How deep will the base and the millings be after compaction? Get both figures, and get them in writing.
- How will it be compacted? With a proper roller, and in layers.
- How will the driveway drain? Where will the water go?
- What upkeep should I expect in the first few years? Top-ups, re-grading or sealing.
- What would the same driveway cost in new asphalt? With the same preparation, so the comparison is fair.
Key Takeaways
- A recycled asphalt driveway is made from asphalt millings: old pavement ground up, spread and compacted cold.
- It costs less than new asphalt and is firmer and tidier than gravel, but it stays rougher, less uniform and more variable in quality.
- Millings suit long rural lanes, parking pads, gravel upgrades and budget first stages.
- New hot-mix asphalt is worth it for the main driveway, low maintenance, snow clearing and long life.
- The base and drainage matter just as much under millings as under asphalt. The saving is in the top layer, not the preparation.
FAQ
What is a recycled asphalt driveway?
A recycled asphalt driveway is made from asphalt millings: old pavement that has been ground off a road or parking lot by a milling machine, or broken out and crushed. The millings are crushed stone still coated in the old asphalt binder. They are spread, graded and compacted like gravel, and the old binder helps them knit together into a firmer surface than loose stone.
Is a recycled asphalt driveway cheaper than new asphalt?
Usually, yes. Millings are made from material that has already been produced once, so they cost much less per ton than new hot-mix asphalt, and installing them is closer to installing gravel than to paving. The site preparation still costs the same either way. Excavation, soft-soil removal, grading and a compacted base are needed under both, so the saving is in the top layer, not the whole job.
Do asphalt millings harden like real asphalt?
They firm up when they are compacted, because the old asphalt coating on each piece helps them bind together, but they do not become the same smooth, sealed surface as new hot-mix asphalt. Compacted millings stay rougher and less uniform in colour. If they are not compacted properly, traffic can loosen the surface and leave it uneven.
How long does a recycled asphalt driveway last?
It depends heavily on the base, the compaction and the quality of the millings, which varies with where they came from. A well-built millings driveway on a good base can give years of service, especially on a rural or low-traffic lane, but expect to top it up, re-grade or re-compact it over time. New hot-mix asphalt on a proper base is the longer-lived, lower-maintenance surface.
Can you pave new asphalt over a recycled asphalt driveway?
Sometimes. Millings can form part of the layer under a new asphalt surface, but research on reclaimed asphalt used as base material found that strength drops and compaction gets harder as the share of old asphalt rises. A contractor should assess whether the existing millings are firm, well drained and deep enough, and may add or replace base stone before paving.
Is a recycled asphalt driveway good for Ontario winters?
It can be, if the base drains well. Freeze-thaw damage comes from water under the driveway, whatever the surface is. A millings surface is rougher and looser than hot-mix asphalt, so take more care with plow blades and shovels, and expect some spring touch-ups on a heavily used driveway.
