Abstract:

The economy concern and depletion of good quality soil resources has forced the pavement engineers to use the locally available soils to achieve economic feasibility. Due to the weak soil properties, it requires replacement of soil in its sub-grade, sub-base and base courses respectively in road construction which affects the major cost of the project. Hence, it may be economical to use the locally available soil as it cuts down cost and sometimes the time of construction. The solutions available for these problems can be: 1) Partial replacement of problematic soil with stabilized soil. 2) Modification of strength of the available soil using, densification techniques. The present study is carried out to check the improvements in the properties of the locally available red and black cotton soils when blended with admixtures like cement, fly ash and rice husk ash in varying percentages. These results are compared with those of the conventional soil. Stone powder, Fly ash and wood ash are mixed in proportions of 5%, 10% and 15% to the dry weight of soil individually. Index properties including Grain size distribution, Specific gravity and Atterberg’s limits; Engineering properties such as Optimum Moisture Content (OMC), Maximum Dry Density (MDD), CBR, Cohesion (C) and Angle of internal friction (Φ) are being studied for stabilized and natural soils.
