Roads Resurfacing Program

Roads Resurfacing Program

With summer underway, so marks the Town’s annual Road Resurfacing program.

How are the roads rated and ranked?

Town roads are inspected and rated twice a year by Town engineering staff to develop a Pavement Condition Index (PCI). PCI ratings include factors such as ride condition ratings and the physical condition of the road.

Once the road is rated, Town engineers use a risk-based formula to rank the Town roads and identify road priorities. The formula is based on PCI (scale: 100-1) x Road Classification (scale: 1-6).


For example,

Road A: 60 (PCI) x 4 (Road Classification) = 240

Road B: 50 (PCI) x 5 (Road Classification) = 250


Road A is considered a higher priority road when compared to Road B;
the lower the road rating, the higher the priority.

Other factors affecting road priorities include:

  • Roads that have a PCI Index of 45 and lower are automatically slated for reconstruction not resurfacing because they are considered too far deteriorated to be effectively rehabilitated.
  • If a sewer or watermain replacement project is planned in the 10-year capital program, only maintenance activities will be completed until reconstruction occurs as part of the project.


What are the types of road resurfacing & reconstruction used?

Road Resurfacing

  • Hot Mix Overlay – A new layer of asphalt is placed on top of the existing road. (Urban Areas)
  • Hot Mix Mill and Overlay – A portion of the existing asphalt road is milled off and a new layer of asphalt is placed on the milled surface. (Urban Areas)
  • Surface Treatment (aka tar and chip sealing) – Asphalt emulsion is sprayed on top of the existing road surface or other base material and is coated with a fine aggregate (Rural Areas)

Road Reconstruction

  • The existing asphalt roads are pulverized and replaced with new asphalt.
  • The existing asphalt roads are excavated and replaced with a new granular base and new asphalt.
  • The existing surface treated roads are pulverized and replaced with new double surface treat emulsion and fine aggregate. It may also include a layer of recycled asphalt pavement.
  • The existing surface is pulverized, graded and compacted with a dust suppressant application.

How much money is dedicated to fixing our roads?

In order to maximize the dollars committed to the Roads Resurfacing program, Town Council approves the annual budget early in the year; thus, allowing for early tendering and favourable pricing.
