Roadwork Guide

Also referred to as patching, the purpose of localised pavement repairs is to quickly repair small areas of asphalt that have deteriorated significantly or where recurring potholes pose safety risks.

Scope of Work

This type of intervention is limited to a specific area and does not span an entire block or street. It is applied to targeted sections where a larger Capital Works project is planned in the near future, within the next five years. This approach helps ensure responsible use of public funds.

About 1.5 inches of asphalt are removed from the road surface and replaced with a new layer of the same thickness. No work is carried out on the road foundation or on underground infrastructure such as pipes or utilities.

• Work period: year-round, with a peak in the spring during the thaw.
• Duration:  usually less than 3 days
• Lifespan: approximately 3 to 5 years

Also referred to as repaving, asphalt resurfacing or road resurfacing is done to renew the road surface over larger areas, such as an entire block or full street segments. Its purpose is to extend the lifespan of the road by addressing widespread surface deterioration.

This type of work is carried out when road conditions show significant wear, such as deep tire grooves, extensive cracking of the asphalt surface, numerous roadway cuts, large potholes, uneven or raised areas, or drainage problems that affect water runoff.

Scope of Work

The work typically involves removing the entire asphalt surface and repairing the road foundation, which is often made of concrete. It may also include rebuilding sidewalks or portions of sidewalks, upgrading street lighting, installing or adjusting catch basins to improve drainage, and carrying out work on underground services. This can include water network repairs and service connections, as well as electrical upgrades performed by Hydro Westmount.

• Work period: de mai à octobre lorsque les températures permettent la pose d'asphalte.
• Duration: usually 6-15+ weeks
• Lifespan: 15-20 years, with crack filling initiatives as required

Maintenance and repair work is a variation of asphalt resurfacing and is carried out about 15 to 20 years after a complete road reconstruction. It applies to larger sections of roadway, such as an entire block or full street segments.

The goal is to preserve the road foundation by removing and replacing only the top layer of asphalt. This approach helps extend the road’s durability and overall service life. At this stage, the road structure remains in good condition, with only minor signs of wear such as small cracks, shallow tire grooves, surface flaking, or occasional potholes.

No work is required on underground infrastructure or drainage systems. Roadway cuts are kept to a minimum, and there are no issues related to road lifting or settlement.

Scope of Work

The work typically includes removing the top layer of asphalt, about 1.5 inches thick, along with minor localized surface repairs. In some cases, small sections of sidewalk may also be rebuilt. All underground infrastructure was previously upgraded during the original road reconstruction and does not require additional work.Works should be scheduled within 15 to 20 years after a complete road reconstruction.

• Work period: from late spring to fall (with some exceptions)
• Duration: 4-8+ weeks
• Lifespan: 15-20 years, with crack filling initiatives as required.
  
  

Road reconstruction involves rebuilding the road and sidewalks from the ground up. It also includes rebuilding or upgrading underground and surface systems, when required, to ensure the long‑term safety and durability of the street.

Scope of Work

This type of project typically includes rebuilding the road foundation and underlying layers, carrying out work on water and sewer networks, upgrading electrical infrastructure in coordination with Hydro Westmount, improving stormwater drainage systems, and making changes to the street layout, when needed, to improve safety or functionality.

• Work period: April through November, often spanning several months depending on the scope of the project.
• Duration: 12+ weeks
• Lifespan: 50+ years, with regular maintenance and repair work required over time, including routine resurfacing that is generally carried out every 15 to 20 years, along with crack filling as needed
