Soil Stabilization of Clayey Soil using Coir Fibre and Lime

In India the soil mostly present is Clay, in which the construction of sub grade is problematic. In recent times the demands for sub grade materials has increased due to increased constructional activities in the road sector and due to paucity of available nearby lands to allow excavate fill materials for making sub grade. In this study coir fibre and lime is mixed with Parent Soil in various percentage ( 0%, 0.25%, 0.75, 1.0% and 5%, 10%, 15%). The main objective of this study is to evaluate shear strength characteristics, Unconfined Compression behaviour of untreated and stabilized soil with coir fibre and lime. Based on the results obtained from standard Proctor compaction test, the ideal MDD and OMC value used for further, unconfined compression test. The present investigation has therefore been carried out with materials such as coir fibre and lime which was mixed with soil to study improvement of weak sub grade in terms of compaction and strength characteristics.
