A Study on Stabilization of Black Cotton Soil Using Fly Ash and Plastic Fibres

Abstract

Abstract Soil stabilization is most important for the construction which is widely used in connection with road pavement and foundation construction because it improves the engineering properties of soil such as strength. Utilization of industrial waste materials in the improvement of soils is a cost efficient and environment friendly method. Stabilization of the expansive soil is studied by using fly ash and plastic fibres. The present investigation is to evaluate the compaction, CBR and unconfined compressive strength of stabilized black cotton soil using fly ash and plastic fibre mixes. The geotechnical properties like compaction parameters and California Bearing Ratio increase in both soaked and unsoaked conditions which indicates the improvement in strength. From these results, it was found that optimum % of fly ash is 15% and of plastic fibres is 1% which gives the maximum increment in the CBR value compared with all the other combinations.
