For this purpose a series of experiments were conducted which include Modified Proctor Compaction, California Bearing Ratio (CBR) and Unconfined Compressive Strength (UCS) tests. A total of four samples of soil - fibre mixture were made with fibre content as 0.15%, 0.30%, 0.45% and 0.60% of dry weight of soil. Other tests for index and physical properties like Atterberg limits, Specific gravity and sieve analysis of parent soil were also carried out. Experimental results revealed that addition of Recron 3S fibre increases the CBR and UCS value of the silty soil. From the results it is also observed that benefit is more appreciable at lower percentage of Recron 3S fibre i.e. 0.15% as compared to higher percentage.

Present paper describes the effects of Tibba sand on soil subgrade strength of silty soil of Kurukshetra. Tibba sand which is found mostly in Haryana and Rajasthan states of India, can play a role of good soil stabilizer. Various experimental investigations which include Index properties determination(Specific gravity, Atterberg’s limits and Wet sieve analysis), Modified Proctor Compaction tests, California Bearing Ratio (CBR) tests and Unconfined Compressive Stregth (UCS) tests were conducted to observe the effects of mixing Tibba sand to silty soil. Tibba sand was mixed with silty soil in various proportions starting from 5%, 10%, 15 % and 20% by weight of soil. Experimental results revealed that Optimum quantity of Tibba sand which should be used in improving CBR and UCS value of silty soil is 5% by weight of soil and after that (from 5 % to 20 %) it shows a declining trend in CBR and UCS value of Stabilized silty soil.
