摘要：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 subbase
applications.
