STUDY ON THE UTILIZATION OF IRON SLAG IN HOT BITUMINOUS MIXES

Abstract

The large amount of industrial wastes asincreased year by year and disposal becomes a very serious problem.Itis necessary to utilize the steel slag waste affectively with technical development in each field. This project wasintended to study the effectiveness of using steelslag aggregate (SSA)in improving the engineering properties of locally produced asphalt concrete (AC) mixes. The research started by evaluating the toxicity and chemical and physical properties of the steel slag. The AC mixes was replaced by SSA. The effectiveness of the SSA was judged by the improvement in indirect tensile strength, resilient modulus, rutting resistance, fatigue life, creep modulus, and stripping resistance of the AC samples. Penetration is influenced by number of lanes, lane width, number and spacing of access points, shoulder presence and width, gradient of the road, driving population etc. The time period normally used for type, usually the passenger car. The capacity is then expressed in passenger car unit (PCUs) per hour. The traffic conditions in India is highly heterogeneous in nature and vehicles do not follow lane discipline in turn causes abrasion on the roads and decreases the life span and results in the cracks and surface loosening of the roads. The superior adhesion Iron slag with bitumen would also minimize potential moisture damage of the Iron slag mix. This will increase the skid resistance and will prevent water from drains and rain to enter into the roads at great extent.
