With the development of a country the amount of waste generated increases. In the recent years, there has been a greater problem to deal with this increasing amount of waste. In the following study, an attempt has been made to deal with growing amount of rubber tire waste by utilizing crumb rubber as an additive with clayey soil in order to analyze its effect on soil properties. The Standard Proctor test and California Bearing Ratio (CBR) tests have been carried out on parent soil and soil mixed with varying percentage of crumb rubber. The results revealed a reduction in the value of OMC and MDD with increasing crumb rubber percentage whereas the CBR has shown an increasing trend till 10% addition of crumb rubber. Therefore, it is suggested that the waste crumb rubber tires can be safely used in the subgrade as a soil binder which will effectively hold the soil with increased strength values
