Asphalt paving in Toronto and the GTA.

What asphalt paving actually involves

Asphalt is the most common driveway surface in the GTA, and the one most often installed badly. The material itself is straightforward: a mix of aggregate and bitumen, laid hot and compacted while it's still workable. What separates a driveway that lasts twenty-five years from one that fails in four has almost nothing to do with the asphalt and almost everything to do with what's underneath it.

Much of Toronto and the surrounding region sits on clay-heavy soil. Clay holds water, water freezes, and frozen water expands. A driveway built on a shallow or poorly compacted base gets lifted and dropped by that cycle every winter until the surface cracks. No amount of good asphalt survives a bad base — which is why we treat excavation and compaction as the actual job, and the asphalt as the finish.

Our construction specification

These are the numbers we build to on a standard residential rebuild. Each one appears on your quote with the measurement confirmed for your property.

Bobby Paving asphalt construction specification

Stage	Spec	Why
Excavation	250–300 mm	Down to stable subgrade. Depth is confirmed on site — clay and fill vary block to block.
Geotextile	Non-woven	Separates base from subgrade so the granular doesn't migrate into the soil over time.
Granular base	150 mm	Placed in two 75 mm lifts, minimum four plate-compactor passes each.
Base course	50 mm HL-8	Coarser mix. Carries the structural load and bridges minor base movement.
Surface course	40 mm HL-3	Finer mix, laid separately. A single 90 mm pour cools unevenly and cracks at the seam.
Grade	2% minimum	Water leaves the surface toward a legal outlet, never toward the foundation.

Rebuild, resurface, or repair?

Three different jobs at three very different prices. We tell you which one your driveway needs during the site visit, and we say so even when the honest answer is the cheap one.

Full rebuild — $8 to $13 per sq ft

Everything comes out down to subgrade and gets rebuilt. This is the answer when the base has failed: alligator cracking across large areas, soft spots that flex under a car, sections that have sunk, or drainage running the wrong way. A typical two-car driveway of 500–650 sq ft lands between $4,500 and $8,500 including tear-out and disposal.

Resurfacing — $4 to $7 per sq ft

A 40 mm overlay on top of the existing surface. Only works when the base underneath is still sound, which we verify before quoting it. Typical range $2,200 to $4,500. Resurfacing a driveway with a failed base is the single most common way homeowners waste money in this trade — it looks perfect for one season and cracks in the same places by the second spring.

Repair and sealing — $1.50 to $3 per sq ft

Crack filling, patching isolated potholes, sealing. Appropriate for a structurally sound driveway that's aging on the surface. Usually $450 to $1,400.

Timing and season

Paving season in the GTA runs roughly April through November. Asphalt has to be laid hot and compacted before it cools, so cold ambient temperatures shorten the working window and hurt compaction. Late spring and early fall are the sweet spot: mild temperatures, less rain delay, and shorter waits than the July peak.

A residential driveway takes one to three days on site. You can walk on it the same day and drive on it after 48 hours in most conditions. Full curing takes several months, during which the surface stays softer than it will eventually be — so keep sharp-edged supports like motorcycle kickstands and jack stands off it through the first summer.

Do you need a permit?

Replacing an existing driveway in its current footprint generally does not require a permit. Building a new driveway, widening one, or cutting a new curb does. The City of Toronto also requires stormwater retention for new hard surfaces above 50 square metres, which in practice usually means permeable pavers rather than solid asphalt.

Rules differ by municipality — Vaughan, Markham and Mississauga each set their own driveway width limits and permit process. We confirm which category your property falls into during the site visit, and we handle the filing when it's needed. See our Toronto driveway permit guide for the details.
