The engineering properties of the decomposed granite soil are not the same as being considerably varied owing to the place of deposit and depth. This paper describes, after investigating the index properties which estimate the degrees of weathering for various kinds of decomposed granite soils, the compressive and shear strength characteristics of these soils with particular reference to the degrees of weathering. The results obtained were summarized as follows; 1) It is desirable to use the ignition loss or absorption for the evaluation of the degrees of weathering. 2) Compressive parameters λ and κ correspond to the degrees of weathering, and the yielding stress p_y almost agrees with the stress at which the particule crushing is stimulated. 3) The irreversibee increment void ratio due to the isotropic consolidation is equivalent to the increment surface area, regardless of any kinds of samples and the water content. 4) There is a unique relationship between the stress ratio at failure (q/p)_f and compressive paremeter κ/λ, as can be seen in the case of clay.
