Highway 10 through Riding Mountain National Park will be extensively tested over the next few weeks, as the park takes a pro-active approach to future road repairs.
Extensive work at kilometre 49 in the park is well underway, but repairs to the remaining portion of the highway are expected in the future.
Workers will be conducting an extensive survey this fall of the structural capacity and uniformity of the existing pavement and underlying subgrade, looking at about 54 km of Highway 10 through the park. The survey will include an intensive review of the park’s construction and maintenance records of the highway, a visual pavement condition survey and weight deflection testing.
The worst areas will also be selected for coring, which will happen about every half-kilometre through the park. Samples will be taken through the asphalt, base layers and into the natural subgrade underneath to help forecast what types of future maintenance will be required.
Road testing will take place from today until Saturday, with core samples being taken between Oct. 22 and Oct. 26.
All work will be done during daylight hours, but traffic may be reduced to one lane during the coring investigation and motorists travelling through the park should watch for posted warnings, speed limits, flag workers and pilot vehicles.
