Micro-Surfacing Saskatchewan’s Roads

Motorists using Saskatchewan’s roads and highways will soon have better road surfaces to travel on as a result of a number of micro surfacing projects that will extend the lifespan of roadways in the province for years.

So far this season, work on major roads has been completed near Macklin, Kindersley and Elrose, and improvements are set to get underway shortly on Highway 7 near Rosetown.

Highways and Infrastructure Minister Don McMorris said the program is an important part of maintaining the quality of roads within the province.
“With more people living and working in the province than ever before, we continue to invest in our transportation network which is essential in getting goods to market,” he said. “Micro surfacing treatments, like the ones scheduled to begin this week, will restore pavement to a uniform surface.”

Pioneered in Germany in the late 1960s and early 1970s, micro-surfacing, a polymer-modified cold-mix paving system that has added capabilities compared with conventional slurry seal, is commonly applied to roads throughout the United States, Europe, Australia and elsewhere around the globe. It has been recognized as a cost effective way of treating a variety of road surfacing problems. Micro-surfacinghas been deemed superior to conventional slurry for its ability to be applied in narrow courses for wheel ruts – depressions on the road surface caused by the wheels of vehicles – without destroying road striping lines.

As well as levelling ruts, the Ministry says the program will help to restore skid resistance, eliminate minor surface problems, prevent hydroplaning and recondition surface damage resulting from weather or traffic deterioration.

The Ministry says the works will help to extend the life of pavement surfaces by five to seven years before any significant repaving will be required.

In addition to the pavement work, the Ministry says a number of new highway construction projects are set to start throughout the province, including grading work on Highway 361 near Lampman, surfacing on Highway 35 near Archerwill, a bridge replacement on Highway 58 near Gravelbourg and construction on Highway 22 near Grayson.
