What is recycled asphalt and is it a good option for a residential driveway in Ottawa or will it fall apart?

Recycled asphalt product (RAP) is becoming an increasingly popular driveway material in the Ottawa area, but it is important to understand both its strengths and limitations before committing.

What RAP Actually Is

Recycled asphalt is old asphalt pavement that has been milled or broken up, then processed through a crusher to create uniform-sized granular material. It still contains the original petroleum binder, which gives it a significant advantage over plain gravel: when compacted, especially in warm weather, the residual binder reactivates slightly and helps the material bind together into a semi-solid surface.

Where RAP Works Well in Ottawa

• Rural and semi-rural properties in areas like Manotick, Carp, Cumberland, and Vars where a paved driveway may not be practical or cost-effective for long lanes
• Temporary surfaces when you plan to fully pave within a few years but need something better than mud now
• Secondary driveways or parking pads behind the main residence
• Budget-conscious projects where the goal is a serviceable surface at minimal cost

Where RAP Falls Short

For a front-facing residential driveway in Ottawa subdivisions — Kanata, Barrhaven, Orleans, Stittsville — RAP is generally not the best choice. It does not achieve the same smooth, sealed surface as hot-mix asphalt. It can soften and become tacky in extreme summer heat, it tracks black residue indoors, and it does not hold up to snowplow blades as well as proper asphalt. Most municipal bylaws in Ottawa do not restrict RAP use, but some homeowner associations in newer developments may have appearance standards that RAP would not meet.

Cost Comparison

RAP is significantly cheaper than new hot-mix asphalt:

• Recycled asphalt (RAP): $2.00 to $4.00 per square foot installed, including grading and compaction
• New hot-mix asphalt: $3.50 to $5.50 per square foot for a standard two-lift installation
• Plain crushed gravel (Granular A): $1.50 to $3.00 per square foot installed

For a 500-square-foot driveway, RAP saves roughly $750 to $1,500 compared to new asphalt.

Installation Tips for Ottawa Conditions

If you choose RAP, insist on a minimum 4-inch compacted thickness over a prepared Granular B sub-base. The best time to install RAP in Ottawa is during the hottest summer months (July and August) when the residual binder activates more effectively during compaction. A heavy steel-drum roller is essential — plate compactors alone will not achieve adequate density.

Durability Expectations

A well-installed RAP driveway in Ottawa will typically last 8 to 12 years with periodic re-grading and top-dressing, compared to 15 to 25 years for a quality hot-mix asphalt driveway. Ottawa's freeze-thaw cycles and heavy snowfall (averaging 200 cm annually) will gradually break down the RAP surface faster than conventional asphalt.
