Resources of engineering materials (sand) used for construction activities are limited, so some other materials should be introduced by changing the sand. Stone dust produced from Stone Crushing Zone appears as a problem for effective disposal. Stone dust can be replaced by sand which is used as a fine aggregate in construction work. In this study, the main concern is to find an alternative to sand. Replacement of normal sand by stone dust will work both solid waste minimization and sand recovery. Stone dust is one of the alternatives to sand which can meet the demand of fine aggregate. In the engineering practice, the properties of existing sub-grades are required for the construction of the earth, thereby improving density and strength of the subgrade. A series of California Bearing Ratio (CBR) tests have been conducted for determination of soaked and un-soaked CBR by using the stone dust as a fine aggregate blended with 10 mm and 20 mm size Coarse Aggregates (CA). A detailed comparison is made for the findings of the CBR tests conducted on samples prepared using natural sand (as a fine aggregate) blended with 10 mm and 20 mm size coarse aggregates.
