Abstract

Hydromechanical performances and pore-structure evolution in in situ lime-Treated soil is influenced by the implemented methodology of execution. In situ lime-Treated soil experiences kneading action during soil compaction; however, little is investigated regarding the contribution of the kneading mechanism towards hydromechanical and pore-structure evolution. This study evaluates the evolution of Unconfined Compressive Strength (UCS), hydraulic conductivity, and pores of different categories in laboratory kneaded soil. The evaluation involves results from lime-Treated soil subjected to different curing times and temperatures. The results obtained from laboratory kneaded and cured soils are interpreted with the one obtained from in situ sampled soil of the same configuration after 7 years of atmospheric curing. The obtained interpretation provides an acceptable insight towards the expected long-Term hydromechanical and pore-structure evolution of lime-Treated soil. Thus, the study highlights the importance of reproducing an implementation mechanism in the laboratory which closely represents the field compaction.
