Leachate-contaminated soil possesses poor engineering properties such as high plasticity, low strength, and excessive compressibility, making it unsuitable for construction purposes. In this study, improvement of leachate soil was attempted using fly ash as an additive material. Different percentages of fly ash were mixed with the soil to evaluate improvements in geotechnical properties. Laboratory tests such as Atterberg limits, compaction, Unconfined Compressive Strength (UCS), were conducted to assess the performance of the soil. The results depict reduction in Plasticity characteristics admixed improvement in compaction characteristics (OMC & MDD) with the addition of fly ash. Unconfined Compressive Strength (UCS) significantly improved up to optimum percentage of fly ash due to pozzolanic reactions and formation of cementitious compounds. Microstructural studies further confirm development of binding gels that enhanced particle bonding and reduced void spaces. Overall, fly ash proved to be an effective and economical stabilizing material for selected leachate soil.
