ABSTRACT
Various soil improvement techniques have been developed to improve soil properties. One of the soil strengthening technique is mixing of randomly distributed discrete fibres to the soil, termed as a “ply soil”. In the present investigation, polypropylene fibres have been chosen as the reinforcement material and were randomly mixed in the soil at 0.1, 0.2 and 0.3% by dry weight of soil. Three different lengths of fibre i.e. 6mm, 10mm and 20mm have been considered as one of the parameters of this study. An intermediate compressible clay (CI) has been used as a soil material in experimental work. The randomly distributed fibre reinforced clay samples were subjected to different types of tests viz. IS: Light compaction tests, unconfined compression tests, consolidation tests, triaxial tests and C.B.R. tests. The results of these tests have clearly shown a significant improvement in the strength properties of the clay.
