Application of Iron Slag at Different Pavement Layers

Reusing waste material in the past decade has got too importance and the reason is emphasizing on environment laws and reducing the pollution of industrial garbage. Steel-making operations has faced with this problem because of producing a large amount of waste material during production which in the case of steel industries ability to recover and using this products, these products create many problems in terms of pollution for environment with regard to their high production volume including slag, dust, sludge, shell sheets and oxide layers in which slag has got the most importance than others because of high production rate. Nowadays, broad research has performed in the world to recycling these side products which have resulted to solutions to recover them. In Iran with regard to the increasing of steel and slag production, research on them and appropriate solutions to use in different applications and reducing environmental pollution seems necessary. This paper addresses the investigation of iron slag at different pavement layers and the influences like frictional resistance, track disruption and bearing strength that it produces
