Bitumen and aggregate estimation aligned with CSA A23.1, provincial MOT specifications, and cold-climate mix design requirements.
MTO (Ontario), MOTI (BC), Alberta Infrastructure, MTMDET (Quebec) and other provincial road authorities.
Canadian mixes use soft bitumen grades (PG 58-34 to PG 64-34) to resist low-temperature cracking.
Asphalt in Canada typically runs C$150–$320/tonne depending on province and spec.

Typical values for common Canadian pavement mix designs.
| Mix Type | Bitumen Content (%) | Density (kg/m³) | Province / Spec |
|---|---|---|---|
| SP 12.5 Superpave | 5.0–6.0 | 2290–2380 | Ontario MTO |
| SP 9.5 Fine-Graded | 5.5–6.5 | 2280–2360 | Various provinces |
| HL-3 Hot-Mix | 5.0–6.0 | 2290–2370 | Ontario MTO |
| SMA (Stone Mastic) | 6.0–7.0 | 2250–2340 | High-volume roads |
| RAP / Recycled Mix | 4.5–5.5 | 2200–2300 | All provinces |
This calculator uses the standard metric formula aligned with provincial road authority specifications across Canada.
Convert thickness from mm to metres, then multiply all three dimensions. Example: A 500 m provincial arterial road, 7.0 m wide, with 50 mm SP 12.5 wearing course: 500 × 7.0 × 0.050 = 175 m³.
Multiply volume by mix density and divide by 1,000 to convert kg to tonnes. Using SP 12.5 density of 2,310 kg/m³: 175 × 2,310 ÷ 1,000 = 404.3 tonnes total mix.
Apply bitumen content percentage to the total mix weight. At 5.5%: 404.3 × 0.055 = 22.2 t bitumen and 404.3 × 0.945 = 382.1 t aggregate. Add 5–10% waste allowance when ordering.
Canadian mixes are governed by provincial road authority specs — not a single national standard. Always confirm density and bitumen content with your specific provincial authority (MTO, MOTI, Alberta Infrastructure, or MTMDET) and the Superpave or Marshall mix design for your aggregate source.
From provincial highways to residential subdivision streets, accurate material estimation is critical for budget control and tender compliance across Canada.
MTO, MOTI, and Alberta Infrastructure project managers use mix tonnage calculations to prepare Bills of Quantities and validate contractor submissions on overlay and rehabilitation contracts. Accurate density values for the specified mix type are essential for payment verification against core samples.

Developers and municipal engineers use SP 12.5 or HL-3 mix calculations to estimate asphalt quantities for new subdivision road construction. Budget estimates include both granular base and asphalt wearing course, with CAD pricing from local suppliers used to set construction contingencies.

Input the length, width, and compacted thickness of your pavement. Canadian SP 12.5 Superpave wearing courses are typically laid at 40–50 mm thickness. Use metres for metric input or switch to feet for imperial measurements.
Choose the appropriate provincial mix — SP 12.5 Superpave (Ontario MTO), HL-3 Hot-Mix, or SMA for high-volume highways. Adjust bitumen content to match your provincial specification. Cold-climate Canadian mixes often use soft binder grades (PG 58-34 to PG 64-34) to resist freeze-thaw cracking.

Canada uses Superpave mix design aligned with AASHTO standards, adapted by each province. Ontario MTO uses SP 9.5 and SP 12.5 designations; BC MOTI, Alberta Infrastructure, and Quebec MTMDET publish their own standard specifications. The CSA A23.1 standard covers general concrete work, but asphalt is governed primarily by provincial road authority specifications.
Canada's harsh winters require bitumen that remains flexible at very low temperatures to prevent thermal cracking. Performance grades such as PG 58-34 or PG 64-34 indicate the bitumen performs at down to -34°C. Southern regions may use PG 64-28, while extreme cold areas in the north can require PG 52-40 or softer.
Canadian asphalt prices typically range from C$150–$320 per tonne. Ontario and BC tend to be at the higher end while prairie provinces are often more affordable. Prices fluctuate with crude oil costs, seasonal demand (paving season is April–October in most provinces), and project scale. Always get current quotes from local suppliers.
SP 12.5 Superpave mix typically has a compacted density of 2290–2380 kg/m³, with 2310 kg/m³ a common default for estimation. HL-3 hot-mix runs slightly higher at around 2290–2370 kg/m³. Always confirm with your laboratory mix design data or contractor's specifications for the specific aggregate source being used.
SP 12.5 refers to a Superpave-designed mix with a 12.5 mm nominal maximum aggregate size, commonly specified by Ontario MTO and other provincial authorities for wearing courses on arterial and collector roads. HL-3 (Hot-Mix Limestone 3) is an older Ontario MTO designation for a 12.5 mm dense-graded hot-mix asphalt — functionally similar to SP 12.5 but designed under Marshall methodology rather than Superpave volumetrics. Most provinces have transitioned to Superpave design, but HL-3 remains common on lower-volume municipal roads. Both mixes have typical bitumen contents of 5.0–6.0% and densities of 2290–2380 kg/m³.
A standard Canadian residential driveway (6 m × 10 m = 60 m²) with a 50 mm SP 12.5 wearing course requires approximately: 60 × 0.050 × 2,310 ÷ 1,000 = 6.9 tonnes of asphalt mix. Allow an additional 5–10% for waste and compaction variability, so order roughly 7.5 tonnes. Wider or longer driveways with a granular base beneath will need additional base course calculation — use the Asphalt Tonnage Calculator for both layers.
The main paving season in most Canadian provinces runs from late April to October, when ambient temperatures are consistently above 10°C. Most provincial specifications prohibit laying hot-mix asphalt when air temperatures fall below 5–10°C, as cold air and substrate cause the mix to cool and stiffen too quickly, preventing adequate compaction. Some contractors use WMA (Warm Mix Asphalt) additives to extend the season slightly into cooler temperatures. Emergency pothole patching can be done year-round using cold-mix or heated repair materials, though permanent repairs should wait for suitable weather. See the Asphalt Repair Calculator for patching quantity estimates.
