Through soil stabilization, unbound materials stabilized with cementican be tious materials (cement, lime, fly ash, bitumen or combination of these). The stabilized soil materials havea higher strength, lower permeability and lower compressibility than the native soil (Keller bronchure 3201E). The method can be achieved in two ways, namely;
