Characterisation of cement-treated crushed rock

Cement treatment for pavement basecourse materials results in the creation of cement treated basecourse which is either classified as “modified” or “stabilised”. The two classifications perform differently in service, with susceptibility to fatigue being the most obvious characteristic delineating the two. This classification methodology is currently quantified based on Unconfined ...
