  • Anti-stripping agent for asphalt mixture including refined slowly-cooled slag, method for preparing the same, asphalt mixture including the same and method for preparing the same
    Patent number: 11365318
    Abstract: The present technology relates to an anti-stripping agent for an asphalt mixture, which includes a refined slowly-cooled slag obtained by processing slag, generated in ironmaking and steelmaking processes, using a specific method, and to a method for preparing the same, an asphalt mixture including the same, and a method for preparing the asphalt mixture. The refined slowly-cooled slag may include 55 to 65 mass % of CaO, 5 to 10 mass % of SiO2, 1 to 5 mass % of Al2O3, and 1 to 5 mass % of MgO.
