Asphalt Patching

Asphalt patching is a common method of repairing areas of pavement with potholes. Potholes occur when water seeps into pavement through unsealed or improperly sealed cracks. The water freezes, expanding and enlarging the crack. When the ice under the pavement melts, a void is left and surrounding pavement falls into the void and forms a pothole.

Asphalt Patch Repair Procedure

CanWest fills the affected areas with hot or cold asphalt mix (cold patch), depending on the season and/or site location.

Asphalt patching and repair can be done for:

• Potholes
• Overlays and edge repairs
