Stabilisation of dredged soil for road pavement

Abstract

Solid wastes are all the waste which arise from human being and mammal activities that are normally solid and are surplus as unwanted material. In this study, the firm waste has been generated by dredging the Dal Lake, which posesses grave dumping and ecological problems around the Dal Lake. In this study, different percentages of dredged material (by weight) were added to normal silty clay soil samples (obtained from Srinagar city in India) and their index properties and compaction characteristics (using Modified Proctor Compaction tests) were determined. Disturbed soil specimens for various laboratory tests were prepared in the laboratory at 0.95dmax and corresponding water content on the dry side of optimum. CBR sample stabilize with dredged soil were experienced for unsoaked and soaked (soaked for 4 days) conditions. Tests results shows great improvement in engineering properties and CBR value with rise in normal silty clay soil contents in dredged soil. therefore, dredged soil has both rewards. First, to avoid the remarkable ecological problems caused by large scale discarding of dredged soil and second, to help in suitable development of environment about well-known dal lake.
