Stabilisation of Closed Landfill Sites by Fly Ash Using Deep Mixing Method
There are many challenges in relation to reusing closed landfill sites due to complex behaviour of creep, settlement and weak shear strength of decomposed wastes, and uncertainties to estimate their engineering properties. Deep mixing method is a ground improvement technique that can be used for chemical modification through solidifying the municipal solid wastes with lime, cement, fly ash or other binders. This paper presents compaction, permeability and shear strength mechanisms of the municipal solid wastes with or without chemical stabilisation using fly ash. The specimen preparation has been designed to simulate the treatment using the dry mixing method. Effect of curing time on properties of samples has also been examined. According to the experimental results and data taken from published literature, it is found that the chemical stabilisation can effectively decrease the permeation, whereas increase the compressibility and compressive strength of the municipal solid wastes.
