Abstract
Considerable efforts have been made to improve the properties of Expansive soils. This paper presents the effects of marble powder and sand on compaction characteristics, Atterberg’s limit, California bearing ratio, permeability and shear strength parameters of clay soil. The clay soil was mixed with marble powder and sand from 30% to 50% and 20% to 40% respectively at an interval of 10%. From the analysis of test results it was found that, liquid limit, plasticity index, optimum moisture content, permeability and cohesion decreased and plastic limit, shrinkage limit, maximum dry density, California bearing ratio and angle of internal friction increased with an increase in marble powder content. From the economic analysis it was found that, marble powder up to 20% is optimum for sand mixed with clayey soil which can be used in strengthening the sub grade of flexible pavements to save the cost of construction.
