So many soil improvement methods have been developed in order to increase bearing capacity of superstructure of the road to be constructed on the soft clayey road base soils, decrease settlements, and increase other strength specifications (CBR,k,MRvalues, etc.). In this paper, lime stabilization of clayey road base soil with high water content and its improvement with geosynthetics (geocell + geotextile) reinforcement and comparisons of these two different improvement methods were made. For this purpose, plate loading experimental comparisons of clayey soil, which had high water content by 10% increasing the optimum water content, were made after it was improved with lime at the rates of 3, 6, and 12%, geotextile reinforcement, geocell reinforcement, geosynthetics reinforcement, and geosynthetics reinforcement + lime stabilization at various rates. It was understood that these improvement methods will not yield sufficient results on clayey soils with high water content on their own, and method of improvement with lime and then reinforcement with geosynthetics yields better results on these types of soils. Only one improvement state among ten different states examined in this study gave the sufficient results for the soil to be used for unpaved roads.

The response model subjected to coupled effect of thermo-hydro-mechano-chemical (THMC) was built in the context of basic theories in the polyporous polyphasic medium mechanics, the mixture theory in the continuum mechanics, and the thermodynamic theories. The finite element discretization of the response model was implemented based on the Galerkin method. The processes of salt leaching and accumulating were analyzed in the numerical results. The results among the numerical results and measured results were compared and discussed. Finally, the solutes migration rule of the soil subjected to the atmosphere eluviations was revealed, and the reasonableness of the coupling model and the finite element method was proved. The agreement between the numerical and the measured results was good, which indicates that the THMC model and finite element program were useful in solving the coupling problems of unsaturated soil. Moreover, the salt dissolution process has a larger effect on the salt movement compared to that of the salt accumulation process. Comparing with the salt leaching effect caused by rainfall, the salt accumulation effect caused by evaporation was smaller.

“…Several damages in highways, airfield pavements and highway embankments have been linked to volume-change behaviour of soil, specifically cracking behaviour due to soil shrinkage [5,6]. The problems due to expansive soils have long been alleviated by adopting suitable ground improvement techniques to reduce the damages to structures found on them.…”

Expansive soils exhibit volume-change behaviour on exposure to moisture changes due to the presence of the montmorillonite mineral. The swell-shrink behaviour of these soils could lead to instability of the structures found on them, specifically the lightweight structures and pavements. Chemical stabilisation of expansive soils has always proven to be more successful in mitigation of swelling, compared to other methods of removal, replacement, and structural alterations. The present study focuses on the behaviour of a representative expansive soil treated with a conventional inorganic additive (lime) and less explored additives like calcium chloride and magnesium hydroxide, with a view to understand the effect of functional group of the inorganic additives in curtailing the swelling behaviour of the soil. The phenomenon of stabilisation is compared in terms of index and engineering properties based on the quantity of additives and curing period adopted. The macrostructural properties are evaluated through the changes in the plasticity characteristics, stress-strain behaviour, swell and permeability properties. The microstructural aspects of the treated soils are determined in terms of specific surface area, pore size measurements and minerology. Microlevel and macrostructural parameters are correlated to understand the soil-additive interaction and to quantify the extent of stabilisation and permanence of the additive induced changes. The lime and Mg(OH) 2-treated samples effectively alleviate plasticity characteristics of the soil. However, strength of the limeamended soil gets significantly improved, contributing to nearly 180% increase in strength compared to 100% and 45% increase for CaCl 2-and Mg(OH) 2-amended soils. Further, the additives also completely nullify the swelling phenomenon. The microstructure properties, SSA and pore size of the treated soils are concomitant with the macrolevel properties, such as permeability, swell and strength characteristics of treated soils, which further confirm the particle orientation of the soil on additive amendment. These analyses give a clear understanding of the orientation of the soil fabric, which dominates the overall behaviour of the soil-additive composites.
