Pavement management program
The Pavement Management Program prioritises and determines how to upgrade and repair the roads surface. Road priorities are based on various tests and software analysis that provide a numerical ranking for each road. In certain cases a core sample helps to identify the quality of the road base and determines the type of treatment required.
While road work can be inconvenient for travellers, the work is necessary to ensure our roads remain safe to use and to manage long-term costs. Crews do their best to schedule and coordinate road work in a way that has the least impact on neighbouring residents, commuters and visitors. Most work happens during the spring and summer seasons, as paving requires warm, dry weather. Crews also ensure they communicate with emergency services so that roads remain accessible during an emergency.

Mill and fill extends the life of existing roadways by twenty years and creates a smooth ride by eliminating the effects of tire ruts and asphalt movement that occur over years of use.
This is accomplished by removing approximately 20 mm of existing asphalt through a process called cold milling, then replacing it with a suitable depth of new hot mix asphalt. The 20 mm of milled asphalt that is removed is recycled and used as a surface treatment on rural roads and lane ways throughout the city.
The asphalt overlay program involves the application of two inches of new asphalt on top of the existing roadway, creating a new driving surface and extending the life of the road. This process is typically performed on rural streets with no curbs and gutters.
Micro-surfacing preserves and extends the life of the road surface by sealing, filling ruts and providing skid resistance. Micro-surfacing involves the application of a dense graded aggregate, mixed with asphalt emulsions, water and mineral fillers, to the road surface. Once applied it takes approximately four to five hours to cure, creating a new stable surface that is resistant to rutting in the summer and cracking in the winter.
Road reclamation creates a new road by grinding the roadway’s existing asphalt and gravel base, then mixing it with new gravel. This mixture is placed on the roadbed, graded and shaped prior to receiving two inches of new asphalt. Road reclamation is typically performed on rural streets with no curbs and gutters.
From April until November, hot mix asphalt is purchased and used for asphalt repairs on all city roads. During the winter months when hot mix asphalt is unavailable, old asphalt that has been collected during the summer is recycled and used for asphalt repairs.
All road markings are re-painted once a year. On roads where there is significant road wear, for example arterials and connectors, centre and lane lines will be painted twice per year. Crosswalks are re-painted once per year and as needed throughout the year.
