Is recycled asphalt a good option for my Ottawa driveway or should I stick with fresh hot-mix?

Recycled asphalt pavement (RAP) is widely available in Ottawa and can be a practical choice for certain driveways, but it comes with trade-offs worth understanding before you commit.

What Recycled Asphalt Actually Is

RAP is milled-up old asphalt from road resurfacing projects. It gets crushed and screened, then either compacted as loose millings or blended into new hot-mix at a plant. Ottawa generates plenty of RAP from municipal road work each season, so supply is usually steady from local yards in Carp, Vars, and along Leitrim Road.

Loose Millings vs. Plant-Blended RAP

Loose millings spread and compacted on your driveway cost roughly $8 to $15 per square foot installed in Ottawa, making them one of the cheapest paving options. They compact reasonably well in warm weather and provide a dark, asphalt-like surface. However, loose millings never truly bind the way hot-mix does. They can shift under heavy vehicles, develop ruts, and wash out along edges during spring snowmelt. Plant-blended RAP, where recycled material is mixed with fresh binder and aggregate at a hot-mix plant, performs much closer to virgin asphalt. Most Ottawa plants now blend 15% to 30% RAP into their standard mixes as a matter of course, so you may already be getting some recycled content without even asking.

Where RAP Millings Make Sense

For long rural driveways in areas like Cumberland, Manotick, or Dunrobin where you have 50 to 150 metres of lane, loose millings over a proper granular base can save thousands of dollars compared to full hot-mix. They handle light residential traffic well and are easy to top up every few years. For a standard suburban driveway in Barrhaven or Kanata where appearance and longevity matter more, plant-blended hot-mix with RAP content is the better investment.

Ottawa Climate Considerations

Ottawa's freeze-thaw cycles, with temperatures swinging from -30°C in January to +35°C in July, are hard on any pavement. Loose millings lack the continuous binder matrix that helps hot-mix flex through frost heave without cracking. If your driveway sits on clay-heavy soil common in Gloucester and Orleans, the frost movement will be more pronounced, and loose millings will shift more than bound asphalt.

Cost Comparison

For a typical two-car Ottawa driveway of roughly 45 square metres, expect to pay $2,500 to $4,000 for compacted millings versus $6,500 to $10,000 for proper hot-mix paving. The millings will likely need refreshing every 4 to 6 years, while hot-mix should last 15 to 25 years with sealcoating.

Making the Right Call

Talk to a local paving contractor through Ottawa Driveways who can assess your specific soil conditions, driveway length, and traffic patterns to recommend whether RAP millings, blended hot-mix, or full virgin asphalt is the right fit for your property and budget.
