| dc.description.abstract | In this study the index properties and swelling potential of soils of Sheno town are examined. The study is conducted with the aim of examining the index properties which are relevant in predicting the swelling characteristics of soils of the study area. Expansive soils of Sheno town, both the black soils as well as the light brown soils undergoes considerable swelling during the wet season. The test results of soils of Sheno town showed that the specific gravity ranges from 2.66 to 2.86. The index property tests showed that the plasticity index ranges from 60% to 78.9% at a depth of 1.5m and 45.2% to 58.2% at a depth of 3.0m.The unconfined compressive strength of soils of the study area ranges from 72kPa to 83kPa at a depth of 1.5m and 82kPa to 93kPa at a depth of 3.0m.The clay content of the soil ranges from 58.47% to 75.0%at a depth of 1.5m and 45.68% to 58.77% at a depth of 3.0m. Free swell tests conducted on the collected samples showed a range from 123% to 165% at a depth of 1.5m and 83% to 120% at a depth of 3.0m.The results of the one-dimensional consolidometer showed that the swelling pressure of the area ranges between 70kPa to 200kPa, the pre-consolidation pressure (Pc) ranges between 150kPa to 290kPa and the compression index (Cc) ranges between 0.285 to 0.389. Soils of the study area are classified both by the USCS and the AASHTO system. According to the USCS, soils of the study area fall in the CH group and when using the AASHTO system all soils fall in group A-7 which cannot be used as sub grade for highway constructions. | en_US |
