How much for a typical Ottawa double-wide driveway in asphalt?

A typical double-wide asphalt driveway in Ottawa costs $6,000 to $12,000 for complete replacement, depending on size, base requirements, and access conditions.

A double-wide driveway in Ottawa typically measures 6 to 8 metres wide by 15 to 25 metres long (90 to 200 square metres), accommodating two vehicles side-by-side. The wide size means you're looking at substantial material quantities and the need for proper structural design to handle the load distribution across the broader surface.

Base preparation is critical for double-wide driveways because the larger surface area experiences more differential settling and frost heaving if not properly supported. Ottawa's 1.2 to 1.5-metre frost depth requires a minimum 300mm compacted Granular B sub-base plus 150mm Granular A base. On Ottawa's prevalent clay soils (common in Barrhaven, Orleans, Gloucester), you'll likely need geotextile fabric beneath the granular base to prevent clay migration. The base alone represents $2,000 to $4,000 of your total cost.

Asphalt installation typically uses a two-lift system — 50mm of HL8 binder course followed by 50mm of HL3 surface course, both compacted with a vibratory roller. Current Ottawa pricing runs $3.50 to $5.50 per square foot for the complete asphalt package. Larger driveways often get better per-square-foot pricing because contractors can work more efficiently with paving equipment on bigger surfaces.

Additional cost factors include excavation and disposal of existing material ($1,500 to $3,000), grading and drainage work to ensure proper 2% slope away from the house, and potential permit fees if you're widening beyond the existing curb cut. Access challenges — narrow lots, overhead wires, or limited truck access — can add $500 to $1,500 to the total.

Timing affects pricing significantly. Peak season (May through September) commands full rates, while booking for mid-summer sometimes yields 5 to 10% savings. Never accept asphalt work after early October in Ottawa — cold weather prevents proper compaction and leads to premature failure.

When to hire a professional: Double-wide driveways require heavy equipment (paving machine, vibratory roller, dump trucks) and precise base preparation that's impossible to achieve with hand tools. The investment is substantial enough that cutting corners on base depth or compaction will cost thousands more in premature replacement within 5 years.

Get three quotes from contractors who specify base depths, compaction methods, and asphalt thicknesses in writing. Quality work costs more upfront but lasts 20 to 25 years with proper maintenance versus 3 to 5 years for budget installations that skimp on base preparation.
