Municipal and provincial governments in Canada are all looking for better ways to deal with their growing pothole problems, but none is properly tracking whether the repairs they do now are effective over time, says the author of a soon-to-be completed study on the roadway menaces.
And few appear prepared to spend the money necessary to ensure what they shovel into the car-crippling craters lasts until longer-term road repairs can be performed, says engineer Dave Hein.

Cities and towns, along with provincial and territorial governments, have been experimenting with different materials and new technologies to tackle potholes.
The cities of Ottawa and Thunder Bay, Ont., Cranbrook, B.C., and Montreal are among those that have experimented with a pothole-filling machine called the Python 5000, which mechanically fills cracks and crevices in roadways B次元官网网址� work normally performed by manual labourers B次元官网网址� in efforts to speed repairs and ensure they are done uniformly.
Others have tested a variety of hot and cold mixes of asphalt and other materials, hoping they find something better than what has been used in the past.
