Cement-Stabilized Subgrade (CSS) Soils

Cement-Modified Soil (CMS) and Cement-Stabilized Subgrade (CSS) are two types of Soil-Cement pavement applications. Both CMS and CSS improve the physical properties of native in situ soils, and both help extend the life of a pavement by providing uniform support via a durable, stable, and typically non-expansive subgrade.
