RE:RE:RE:Cematrix Road Base for Ontario Municipal RoadI have been to the St.Agatha site and have pictures of it before the final paving. I wish I knew how to post the pictures on here. Anyways, that study was done to see at what depth cellular concrete is most effective. It is more of of a phase 2 or 3 study to establish how to make the use of cellular concrete the most efficient and effective. It was done because previous studies have shown it to be a very effective way to extend road longevity. They have done studies on highway #9 between Dixie Road and Winston Churchill Road on peaty soils between 5-10 years ago. They are still hanging in well.
