Performance Evaluation of Municipal Solid Waste as a Sustainable Backfill Material in RE Wall
Looking at the present scenario of increase in population and demand of modern life style, sustainable municipal solid waste (MSW) management may always remain a matter of concern. The major objective of this study is to use existing Pirana landfill MSW (Ahmedabad, Gujarat) as fill material for reinforced earth (RE) wall with uniaxial geogrid reinforcement and evaluate its load-displacement characteristics under gradual incremental loadings. To fulfill this objective, sand, MSW, sand sandwiched between MSW, and mix 1(sand):3(MSW) composites were used as backfill material under dry condition. Lateral displacements were measured at 4 locations on facing panel (wall) for each load increments as 20%, 40%, of maximum theoretical load. For the most efficient MSW composite, the effect of degree of saturation and particle size characterization was measured and evaluated using displacement and earth pressure theories. From results and analysis it is concluded that MSW can be effectively used as backfill material in RE wall based on MSW-reinforcement interaction and tensile strain compatibility of reinforcement playing role in load dispersion under maximum loadings.
