COMPARATIVE STUDY OF STABILIZATION OF EXPANSIVE SOIL USING JUTE FIBRE AND POLYPROPYLENE FIBRE

Abstract

Expansive soil are considered to be unsafe with reference to safety of the structure in serviceability aspects, and needs to be tackled in a well engineered manner, if it should be used as a foundation soil. Several ground stabilization techniques are used to enhance the property of expansive soil, such as lime and cement stabilization. In this report the Jute fibre and polypropylene fibre are used to enhance the engineering properties of the soil. The main goal of this study is to understand the effectiveness of Jute fibre and polypropylene fibre when it is reinforced with soil in different proportions. The effect of fibre reinforcement with expansive soil was observed by a series of laboratory test such as index property test, compaction test, unconfined compression test, CBR test, free swell index test, Brazilian test (Indirect tensile test) , scanning electron microscope test. All the test result shows that there is an improvement of soil when it is reinforced with jute fibre and polypropylene fibre and in this report on the basis of engineering property of soil a comparative study was done with Jute fibre and polypropylene fibre.
