摘要：Expansive soils pose problems to civil engineers in general and to geotechnical engineers in particular.They cause damage to structures founded in them because of their potential to react to changes in moisture regime.They undergo severe volume changes corresponding to changes in moisture content. Because of their potential toundergo volumetric changes, civil engineering structures such as foundations, retaining walls, pavements, airports,sidewalks, canal beds and linings are damaged. They swell or increase in their volume when they imbibe water andshrink or reduce in their volume on evaporation of water. Because of their alternate swelling and shrinkage, they resultin detrimental cracking of lightly loaded structures. Various innovative practices have been devised to counteract thevolume change problem and to safeguard the structures. Various remedial measures like soil replacement, moisturecontrol, pre-wetting, lime stabilization have been practiced with varying degrees of success. However, these techniquessuffer from certain limitations with respect to their adaptability, like longer time periods required for pre-wetting thehighly plastic clays, difficulty in constructing the ideal moisture barriers, pulverization and mixing problems in case oflime stabilization and high cost for hauling suitable refill material for soil replacement etc.In this present work, an attempt is made to study the strength and deformation behaviour characteristics of chemicallystabilized expansive soil sub-grades using model tanks simulating field conditions in laboratory.
