It is acid rock stone multiple (Acid Rock Drainage in the case of the stratum where pyrites thing was done attendant of in the public works spot: ARG) occurs and environmental pollution, Concrete corrosion, With crack outbreak and an incision magazine of a makeup bottom by the sulfuric acid swelling that does not get if buy it, generate problems such as instability. Waste rock is created when a road is constructed through rock layers containing pyrite and arsenopyrite. It could be reusing resource or hazardous waste depends on the treatment and reusing methods. However, its reuse and treatment are very limited since it flew out into acid rock drainage water with high percentage of heavy metal contained in waste rock. The main object of the study is to provide basic data for studies that focus on appropriate treatments of waste rock by analyzing pH change of an effluent and leaching characteristics of heavy metals when waste rock created during a road construction meets water and air.
