The main objective of this study is to investigate the effect of RECRON fibers in BLACK COTTON soil. Civil engineers face various problems while designing the foundations on highly compressible Black Cotton soil due to poor bearing capacity and excessive settlement when it comes in affinity of water. Most of the soil especially Black Cotton soil available in our surroundings is such that it has good compressive strength, adequate shear strength but is weak in tension or has poor tensile strength. To overcome the same, many researchers have concentrated their studies on soil improvement techniques by developing new such materials or a combination of such materials. In this study of Black Cotton soil along with Recron fibres is used. The Recron fibres of different aspect length (6mm, 12mm and 18mm) is mixed properly with soil mixture in varying percentages (0.50%, 0.75% and 1.0%) by dry weight of Black Cotton Soil. The main objective is to study the index and engineering properties like California Bearing Ration (CBR), Shear strength parameter (c & ?), Atterberg's limits at all above mentioned percentages. The test results would indicate improved geotechnical properties of Black Cotton Soil. The optimized results are obtained on using 0.75% of 6 mm length Recron fibre as its use improved geotechnical properties like shrinkage limit by 1.88 times when compared with normal Black Cotton soil. California bearing ratio increased 2.67 times, Liquid limit decreased by 0.94 times, cohesion value increased by 4 times, moreover free swell index decreased by 0.42 times when compared with the normal Black Cotton soil in which no Recron fibre was used.
