City working on potholes after cold winter, rapid temperature change
It’s no surprise that drivers are currently dealing with a litany of potholes they have to avoid on Grande Prairie streets.
After the second coldest February in the last 50 years in the Swan City, to go with a rapid temperature change to above zero days (some in double digits), the city has plenty of ruts and divots that need tending to.
“It is high pothole season, for sure,” said Transportation Manager for the City, Robert Carroll. “We get these warmer days and cooler nights, that’s really what makes them. The water that’s sitting on the road because of the snow melting gets into the cracks and crevices of the road and freezes and thaws. That expansion and contraction causes the pothole to be created.”
City crews are already out filling many potholes around the city, noted Carroll, using a cold-mix asphalt. The cold-mix is a cheaper option to a hot-mix asphalt and is a more temporary option. However, before a hot asphalt filler can be used effectively, night time temperatures would need to stay well above zero degrees and the ground would have to be fully thawed at the time of repair.
