  • Abstract:
  • Due to rapid urbanization, industrialization and growth of population there is tremendous increase in construction activities, has led to scarcity of land with good bearing capacities thus forcing the construction over sites deemed unsuitable for such activities. To improve the geotechnical properties of soil of such sites soil stabilization methods are adopted. Stabilization is an effective alternative for improving soil properties, the engineering properties derived from stabilization vary widely due to heterogeneity in soil composition. The technical modification of soil is carried out by addition of stone dust to original expansive soils in the range of 0 to 60% with an increment of 10% viz. 10%, 20%, 30%, 40%, 50% and 60%. The effect of stone dust on liquid limit, plastic limit, plasticity index, dry density, optimum moisture content and their CBR values are computed. The economics is computed for the different percentages of stone dust added to the soil and their cost arrived for these percentages are computed.
