Resurfacing work has been completed on a four-lane, 13-mile stretch of the Trans-Canada Highway in Manitoba. The eastbound lanes were resurfaced with concrete while the westbound lanes used asphalt. Ron Weatherburn of Manitoba Infrastructure and Transportation says although the department typically uses asphalt, concrete has a longer lifespan. "It gives us a very good comparative test on how concrete compares to asphalt and how the price of concrete compares to asphalt for basically the same road," he says. Analyzing both materials on the road could take 20 to 30 years, he said.
