RE:RE:check this outSergey Averyanov from the university of Waterloo did a paper on the use of cellular concrete as a sub base for road construction. Google it. There are several articles referencing this topic. If our governments ever clue in, this could become a standard. The soils in southwestern Ontario and Michigan are very high in organic matter and water saturated making them weak for road construction. That's why they are always breaking up. WOW! This could be the solution. There would work for decades but in the long run the roads would last much longer, hence, saving money.
