Sulfate soil stabilization with magnesium binders for road subgrade construction

This paper analyzes the ability of magnesium oxide-based additives to stabilize a low bearing gypsum marly soil, in order to reach subgrade requirements. This soil was not adequate for stabilization with lime or cement because of its high sulfate content. Binders considered in this investigation were composed of three reactive Mg products and byproductsSulfamag, both with and without ground granulated blast furnace slags (GGBS).
