2. When is this type of miscellaneous asphalt repair work conducted?

The Miscellaneous Asphalt Repair program begins once the frost is out of the ground, typically in early May, and lasts through September.

The work is publicly tendered and awarded to a pre-qualified contractor.

This repair program adheres to the City of Calgary’s Community Standards Bylaw for hours of work:

  • 7 a.m. to 10 p.m. Monday through Saturday
  • 9 a.m. to 10 p.m. on Sunday and Statutory holidays

3. What are the contractor responsibilities?

The contractor will deliver a notification letter to affected properties, outlining the proposed work schedule. In the event the schedule changes, typically due to inclement weather, the contractor will notify affected property owners as soon as possible.

Barricades and “No Parking” signs will be placed on affected roads segments at least 12 hours prior to the start of work. In some cases, vehicles with arrow boards and flag personnel will be used to direct traffic and ensure safety.

4. What are the benefits of this program?

The repairs restore the structural integrity of the road and extend the service life of the roadway segment while improving ride quality. All materials removed during the repair are recycled.

5. How are these miscellaneous asphalt repairs completed?

The repair area is identified and underground utility locates are performed. The repair area is excavated and materials are deposited offsite for recycling.  A geo-textile fabric is placed on the sub-grade and/or sub-base level to increase the strength of the area.  New gravel materials are then placed over the area and compacted to standard specifications.  The final step to this process is paving the surface within the repair area.

All work is performed to comply with the most recent version of The City of Calgary Roads Construction Standard Specifications for the roadway classification where repair is required.

6. What can you do to help?

  • Please do not enter the repair areas along the roadway, until all barricades and other signage have been removed by the contractor. Barricades will be removed when the roadway is safe to travel on.
  • Plan ahead by parking on an adjacent roadway until the repair area has been completed.
  • Refrain from having lawn sprinklers overspray water onto the roadway immediately before and during work activity.
