Engineering properties of expansive soil varies with the variation in moisture content and due to its swelling and shrinkage characteristics, it poses a serious threat to strength and stability of structure constructed over it. In the present scenario of catastrophic environmental degradation as a side effect of industrialization, urbanization and modern manufacturing processes, new innovative ideas of converting the waste into useful product in a way beneficial for use and recycling. This work deals with the use of quarry dust and sisal fibre for improvement in UCS and CBR values of clayey soil. Laboratory tests like Modified Compaction test, California Bearing Ratio (CBR) and Unconfined Compressive Strength (UCS) were conducted on plain soil, plain soil with different percentages of quarry dust (10%, 20%, 30% and 40%) and plain soil plus optimized QD (70:30 soil - QD) plus sisal fibre (0.5%, 1.0% and 1.5%) at two different lengths of 10 mm and 20 mm. The optimum combination recommended for clayey soil is 30% quarry dust with 1.5% sisal fibre of 20 mm length. The UCS as well as CBR value of clayey soil mixed with 30% quarry dust with1.5% sisal fibre of 20 mm length is increased by 665.31% and 115.51 % respectively. This shows that sisal fibre and quarry dust have the potential to improve the properties of clayey soil.
