Accumulation of solid waste is another serious problem faced by the world for which huge area of land is required for its disposal. Alternatively, engineers try to utilize these solid waste materials in the civil engineering construction based on its feasibility or suitability on their performance. The main objective this study is to investigate the suitability of solid waste materials such as human hair fibers in the process of soil subgrade stabilization as a reinforcement which can replace conventional commercial fiber materials. The influence of reinforcement parameters i.e. fiber content on Kaolinite clay will observe through a series of laboratory tests such as consistency limit tests, compaction tests and unconfined compression tests. This project concluded that the moisture content of soil without human hair fiber is found to be 18.75%. And the moisture content of soil with human hair fiber is found to be decreased as percentage of human hair increased. The specific gravity of soil without human hair fiber is found to be 2.769. And the specific gravity of soil with human hair fiber is found to be decreased as percentage of human hair increased. The free swell test value of soil without human hair fiber is maximum and it is decreased as percentage of human hair increased in soil. Hence degree of expansion is low and degree of severity is non-critical. The maximum dry density (MDD) in standard proctor test of soil without human hair fiber is found to be 1.534 g/cc, which is increased as percentage of human hair increased. Optimum moisture content (OMC) is found to be 10% in soil without human hair fiber and increased as percentage of human hair increased. From Consistency limits test, it is found that the effect of fiber inclusion on consistency limits were minimal, however it was observed that with the increase of human hair fibers content there was a slight increase in the liquid limit and slight increase in plastic limit thereby increasing the plasticity of soil.
