This structure derived from compacting the soil at different water contents and energy levels can have a substantial effect on its shear strength. While the shear strength with varying suction can be estimated based on the saturated shear strength parameters and the unsaturated angle of shearing resistance (0b), limited studies have explored the variation of strength properties with different compaction states. In this paper, the shear strength of a silty sand soil was investigated using a conventional direct shear box under constant water content condition. The tests were conducted on specimens prepared by Proctor compaction with three different normal pressures. the shear strength parameters were obtained and modelled in terms of ultimate states.
