MANUFACTURING METHOD FOR ASPHALT CONCRETE FILLER USING SLAG

摘要

PURPOSE: A manufacturing method of filling material for asphalt concrete using slag is provided to enable replacement of fillers by using electric furnace reducing slag, thereby lowering pavement cost. CONSTITUTION: A manufacturing method of filling material for asphalt concrete using slag comprises next steps: pulverizing coagulated reducing slag of an electric furnace(100); spraying steam on the pulverized slag particles(200); and drying the slag particles(300). The pulverizing process comprises next steps: primary pulverizing the coagulated reducing slag by using a jaw crusher; secondary pulverizing the slag particles by using rod mill; and pulverizing the slag particles with ball mill.
