Impact of moisture mobility on compression characteristics of MSW through soil structure measurements

Abstract

The aim of the present research work is to characterize in situ municipal solid waste (MSW) of Pirana landfill, Ahmedabad and study the flow of water through MSW. A series of compaction test were carried out on dry and wet side of optimum and its structural mobility was determined. Suction characteristics, compressibility characteristics and soil microscopy under constant mobility of moisture and its variational flow path into solid surface and subsurface was evaluated. The results indicate that structural compactness of solid particles which are covered with moisture and chemical diffraction of partial organic matter and its overall effect can be well studied through this type of approach. Suction of MSW is affecting the compression characteristics of MSW and soil microscopy helped in understanding role of drying and wetting under constant degree of compactness and its effect on MSW as hydrodynamic force.
