Roads, Highways & Infrastructure

Interesting. I wonder if there are any paving machines out there that both pick up and grind concrete while laying asphalt?

It would be a multi-month process, like when the SW Ring Road was repaired/replaced in Edmonton.

The biggest problem with that stretch of Deerfoot is that it was originally concrete. Every expansion joint across the road lifted and was horrendous to drive on. maybe 15 years ago they put approximately 12 inches of asphalt on top of the concrete. It didn’t seem to bond very well because the seams split between the lifts and pot holes seemed appear within a few years. Not sure what they can do besides a complete rebuild

When it was concrete, the expansion joint seals seemed to need replacement every year or two. Calgary's freeze-thaw cycle exact a toll

I'm curious how Memorial will work when it gets to Chestermere, will it just die at Rainbow Road?

In 2014 Chestermere approved the "Waterbridge" ASP with plans to extend Memorial to Rainbow road, with a jog north to avoid wetlands
