Abstract
The studies of decomposed granite soils in undisturbed state have been done by means of new sampling and testing technique. But because of the poor situation with regard to relevant literature, the classification system for engineering purposes have not been established, so that these results of studies on the sample taken from various localities do not have compatibility with each other.
The paper proposes a classification system for engineering practice in the decomposed granite soil on the basis of physical and mechanical properties.
