Abstract
Municipal Solid Waste is a heterogeneous mixture of various materials such as food, glass, soil, ash, plastic, etc. Since there are no generally accepted sampling and testing procedures for waste materials, principles of soil mechanics. A good understanding of the properties of unsaturated Municipal solid waste is required for the design of the underground pipelines. Settlement prediction is an important issue to guarantee any post-closure structures on landfills. The present study is an attempt to determine the consolidation characteristics of saturated and unsaturated MSW from the Pirana landfill site, Ahmedabad (India) using a large size Consolidometer having an aspect ratio of 1:0.635. At present five tests were conducted on saturated municipal solid waste for 100% saturation and five on unsaturated MSW keeping a degree of saturation=50% at different water contents. The tests were carried out at the pressure of 20kpa, 40kpa, 80kpa, 160kpa, and 320kpa respectively. The consolidation settlement resulted in both types of waste being compared. It was concluded that the saturated MSW compacted on the dry side of the optimum has less settlement compared to the MSW compacted on the wet side of the optimum while the time taken for the unsaturated MSW was slightly higher as compared to that of the saturated MSW.Q
