Dredged soil is a solid waste generated from dredging of river/lake/pond/channel etc., which possesses low bearing capacity and high compressibility. Large amount of soft soil deposits of solid waste generated by the dredging of the flood spill channel as a part of its regular maintenance in Srinagar City. Concern over the environmental effects of dredging, disposal and the increasing unavailability of suitable disposal sites, has put pressure on characterization of the material. Although these dredged soils are generally considered as waste due to the poor engineering properties, this material can be valuable resource for many practical purposes, such as fill material, landscaping, agriculture, reclamation, creation of islands, constructing wetlands for water quality improvements, wildlife habitat wetlands, landfill covers, subgrade construction and amongst others. Disturbed soil specimens were collected from different sites of the flood channel and various soil tests like gradation, specific gravity, consistency indexes, light compaction, unconfined compressive strength, and direct shear stress were conducted. Specimens for various laboratory tests were prepared at 0.95 γdmax and corresponding water content on the dry side of optimum. The results of three samples were compared and the weakest soil specimen was selected for treatment. The silty soil was added to the dredged soil in varying percentage of 20%, 40%, 60%, and 80%. The tests were conducted with the stabilized soil at these percentages and the effect of stabilization was analyzed. CBR samples of stabilized dredged material with silty clay soil were tested for un-soaked and soaked (soaked for 4 days) conditions. CBR values increased with the increase in normal silty clay soil content in the dredged soil. It was observed that 60% of silty soil is an optimum amount to maximize the CBR value of the dredged soil. Thus, stabilization of the dredged soil showed a tremendous improvement in its engineering properties and hence, using dredged soil has two-fold advantage. First, to avoid the environmental problems caused by the large-scale dumping of dredged soil and thus to help the sustainable development of the environment around the flood spill channel. Second, to use the dredged material effectively as the subgrade construction material.
