In India there are many steel rolling mills, producing billets/ingots everyday, these billets/ingots contain 20% of steel slag by weight. This slag is crushed and steel is again extracted from the slag about 1% of both finer slag and steel is obtained and 18% is wasted again. After conducting various tests, the properties obtained are similar to that of natural aggregates. Properties like gradation, impact value, crushing value, abrasion value of aggregate are within limits of Ministry of Road Transport and Highways (MORTH). Also the California bearing ratio (CBR) value is more than the natural aggregates. By utilizing this slag in roads, the waste material will be used and slag will not cause any harmful impact on the environment and also natural aggregates can be conserved. The basic aim is to make different mix proportion of natural soil and slag and check its consistency.
