Weather causes challenges on local roads
Kamloops, B.C. - Unpredictable and inconsistent weather conditions this winter have created several challenges on local roads. The city is experiencing an abnormally high number of water main breaks and potholes due to a more frequent freeze-thaw cycle than normal.
Sunday evening a water main break occurred on the feeder main servicing the Juniper area. This break was caused by the sudden temperate change and is unrelated to the Highland Drive construction project. Crews worked throughout the night to restore service for the following morning.
Potholes are formed when water seeps into small cracks in the asphalt and freezes. The expansion of the ice in the crack causes the asphalt to crumble, and through repeated freeze-thaw cycles a pot hole eventually forms. With the abnormal freeze-thaw cycle this winter, potholes are worse than normal on Kamloops roads.
During the winter months, conventional hot mix is not available and holes must be temporarily filled using a hot recycled asphalt mix or a cold mix material. Unfortunately the repaired potholes are susceptible to the same freeze-thaw cycle and at times require to be filled repeatedly until a more permanent repair can be scheduled.
As the weather warms up, crews will be working hard to repair the potholes with conventional hot mix, but in the meantime, please use caution while driving.
Report potholes by phoning the Public Works Center at 250-828-3461 or by using the MyKamloops mobile app, available for download at www.kamloops.ca/mobileapp.
