In order to examine the effect of the water content and density on the shear strength properties, rained shear tests were carried out on decomposed granite soil whose water content and density differ during compaction. As a result, the strength properties of the compacted decomposed granite soil are not effected by the water content. The cohesion is nearly 0 when p d0 1.7 cubic-cm and increases as the dry density increases when p d0 1.7 g/cubic-cm. The internal friction angle increases lineally as the dry density increases. Correcting the dilatancy effect reduces the fixed strength coefficients. The higher the density of the sample, the bigger the correcting quantity becomes. In addition, the shear tests results for unsaturated soil shows that the application of suction influence the cohesion
