Index properties are the properties of soil that help in identification and classification of soil. This study is aimed at evaluating index properties and compaction characteristic of black cotton soil found in part of Wolaita Sodo City. Four disturbed samples were collected from areas of the city which is covered by black cotton soil. Different laboratory tests such as sieve analysis, Hydrometer analysis, Liquid limit, plastic limits, and specific gravity and standard compaction tests were carried on the samples. All the analysis was carried out in line with the ASTM testing procedures. Particle size distribution test result showed that the fine fraction (<0.075mm) of investigated soil is in ranges of 84.84% to 95.74% and clay fraction is in the range of 44.17% to 51.01%. Consistency limits test result indicated that the liquid limits, the plastic limits and plasticity index are in the ranges of 78.51% to 87.68%, 36.53% to 36.67% and 40.86% to 51.01% respectively. From standard compaction test it is found that maximum dry density/MDD/ and optimum moisture content/OMC/ of the soil is in the ranges of 1.21g/cm3 to 1.28g/cm3 and 33.33% to 42.39% respectively. Thus the soil in the investigated area will be classified as A-7-5 as per AASHTOO soil classification system and as highly plastic clay (CH) and/ or highly plastic inorganic silt(MH) according unified soil classification system.
