Annual Paving Program
The City of Calgary’s annual paving program runs each year from mid-June through October and includes approximately 130 locations. Please note, locations may be added, removed, or delayed due to budget availability.
The paving program is comprised of two steps: the repair or replacement of concrete sidewalks, wheelchair ramps, and curbs and gutters and, in the same section, the repair or replacement of asphalt roadway. This ensures the best use of resources and budget and minimizes the impact the paving program has on citizens.
Projects take a few days to twelve weeks to complete. The season is short and the work requires dry conditions so City crews and contractors work seven days a week. Work typically takes place 7 a.m. to 10 p.m. Monday through Saturday and 9 a.m. to 10 p.m. Sundays and Statutory holidays. Nighttime work is occasionally necessary to complete work on major roadways, or to ensure there is minimal impact to traffic during rush hour.
Paving dates can be found on the Roadway activities map. Please note, locations may be added, removed or delayed due to budget availability.

Frequently Asked Questions
Each year’s paving program includes approximately 100 locations where City and contracted crews are replacing damaged asphalt and concrete.
Use the Calgary Roadway Activity Map to see this year’s paving projects, next year’s tentative paving projects and where The City has repaved in the last two years.
Planned paving work is impacted by:
- Utility coordination – if a utility in the area needs repair or replacement, TheCity will delay repaving until underground utility repair is complete. This minimizes the impact on the community and ensures efficient use of resources and budget; and
- Weather conditions – weather needs to be warm and dry for paving work to take place. If the season is atypically wet or cold, paving work may need to be delayed until the following season.
The City follows a multi-step process that aligns with industry best practices, to objectively evaluate the condition of Calgary’s road network and identify priorities for each paving season.
Step 1: Annual Condition Survey: City crews conduct sample inspections and record the condition of Calgary streets. Both the surface condition of the road as well as the condition of the road sub-structure is evaluated.
Step 2: Data collected during the Annual Condition Survey is analyzed using an advanced modelling system called the Pavement Management System. This system uses the defects in the surface of each street to determine deterioration rates and objectively establish the overall roadway condition.
Step 3: The overall roadway condition generated by the Pavement Management System is translated to the Pavement Quality Index (PQI) where road conditions are rated from 0 (worst) to 10 (best). The PQI of a road may change from year to year. The Visual Condition Index, or VCI, is a subset of PQI data.
Step 4: The Pavement Management System forecasts multi-year models to identify the correct treatment (crack sealing, micro-surfacing, repaving, etc.) at the right time for specific roads. Priorities will be adjusted so that major infrastructure projects, utility replacements, or budgetary changes are taken into account. This ensures paving budgets are used effectively for the whole roadway network.
Base repairs Permeable fabrics, which strengthen, reinforce and improve drainage, are used to repair alligator cracking and distortion caused by settlement or heave. Installation involves excavating the area, putting the permeable fabrics in place, laying down and compacting new gravel and finally repaving the road surface.
Crack sealing keeps excess moisture from penetrating asphalt and preventing further cracking, potholes and deterioration of the road. As soon as the sealant pouring into the crack is dry, the road can be driven on.
Microsurfacing is similar to crack sealing, however, instead of being applied to a single, small area it is applied across the entire road. This cost-effective solution slows down the natural deterioration of the road and preserves road lifetime without costly and disruptive construction. Learn more about micro surfacing – an innovative solution.
Pothole repair is a major component of our city’s roadway maintenance. The City of Calgary fills over 20,000 potholes each year. Explore the annual pothole repair program to learn what causes potholes and how The City repairs them.
Repaving is when the old pavement surface is milled away and new asphalt is laid down. To learn more about the paving process, please see the road work brochure. Look at this year’s paving schedule to see where The City is repaving this year.
Road reconstruction consists of completely removing and replacing an existing road and its substructure. This is the most costly rehabilitation method, and a roadway only qualifies for full reconstruction if: it is extremely deteriorated, other treatments (such as repaving or spray patching) will not be effective, and the cost of other repairs will be higher than the cost of reconstructing the road. A fully reconstructed road will last up to 20 years.
Slabjacking creates a solid foundation under pavement to correct settling in the road. Holes are cored into the settled roadway and grout is injected to fill any voids. The road is raised and leveled, and finished to match the existing roadway.
Spray Patching is a quick, efficient, and cost-effective way to repair cracked and damaged pavement using an emulsified mixture of asphalt and gravel. Large cracks, potholes, localized raveling, alligator cracking and gaps at the lip of gutters can be corrected quickly. The road can be driven on almost immediately after the repair and after two weeks, the patched areas blend into the surrounding asphalt.
