Abstract: This research work has been done mainly on the compaction characteristic (OMC-MDD, UCS) and strength properties (CBR Values) of expensive soils such as clayey soil. The engineering strength properties of expensive soils (clayey soil) such as compaction characteristics and bearing capacity can be improved by stabilization process of the soil. These properties can be improved by controlled compaction using the mechanical equipment’s or by addition of suitable admixtures like cement, fly ash, lime or by reinforcing the soil with shredded tyre, crumb rubber, plastic waste etc. But in recent years, tyre chips and lime are used very widely for stabilizing the soil, because these are economical than the other admixtures and are abundantly available in the market, so in this work lime treated shredded tyre has been used to improve the various strength properties of natural soil. Lime has been used as a binding material and also used for the treatment of the shredded tyre to make the tyre surface rougher. The objective of this work is to investigate the strength properties of natural clayey soil reinforced with different percentages of lime treated shredded tyre taken by the weight of natural soil and fixed percentage of lime as a binding material. A series of Standard Proctor Tests, Unconfined Compressive strength (UCS) tests and California Bearing Ratio (CBR) tests are being conducted on both the natural soil and reinforced soil with varying percentages of lime treated shredded Tyre (4%, 8%, 12% and 16%) by weight of natural soil and fixed percentage of Lime (10%).The value of MDD increases from 1.75g/cc to 1.93g/cc at 12% of tyre and 10% of lime , the value of UCS also increases from 3.35kg/cm2 to 5.63kg/cm2 at 12% of tyre and 10% of lime and the CBR value will also increase from 3.89% to 10.65% at 12% of shredded tyre and 10% of lime.
