ASPHALT COMPOSITIONS USING WASTE PVB FILM AND MANUFACTURING METHOD OF THE SAME

摘要

The present invention relates to an asphalt composition prepared by using a waste PVB film, and a preparation method thereof. The method is used to prepare an asphalt binder using the waste PVB film separated from vehicle front glass waste in order to recycle the waste, thereby increasing the vehicle scrap recycling rate and reducing waste treatment costs. The method is used to prepare an intermediate temperature asphalt composition by using the waste PVB film in order to reduce the use of petroleum-based fuels for heating asphalt. By using the waste PVB film, the cost-effectiveness of the intermediate temperature asphalt composition is enhanced compared to a method using wax or resins.
