The depletion of resources is a major issue in the civil engineering from which the road construction cannot be excluded. Because of the extensive road construction, the aggregate demand is huge and causing lots of blasting, quarrying, crushing etc is carried out and are consuming energy as well, and the aggregate materials are depleting fast becoming short in supply. On the other hand, industrial by-products and locally available materials are causing environmental and dumping problems, however these can have a application in road constructions. In this study we undergo series of tests on two types of materials one is steel slag, and the other is locally available gravel in the sub-bases. The study concerns chemical composition, phase composition, toxic metals present in the slag and its leaching water, whereas its gradation and other physical properties are observed by undergoing tests. Partial amount conventional crushed aggregates are mixed in proportions to satisfy the desired grading mandatory by the Ministry of Road Transport and Highways. The percentage of the slag and gravel that can be used in sub-base layer is found to be 80% and 50% respectively. In case of gravel, cement was also used in required quantity to get the desired strength. It is observed that both the steel slag and hard gravel have excellent properties and can be used in the road base and sub- base applications.

Steel slag, XRD analysis, toxicity, modified proctor test, etc.
