Abstract

To provide suggestions for the development of asphalt modification technology, this paper developed a calculation model for energy consumption and emissions during high-temperature storage of asphalt by the heat balance relationship. Referring to the life cycle assessment (LCA) method, it compared the energy consumption and pollutant emissions of dry and wet modification processes in the production, transportation, and storage of modified asphalt. The results show that adopting a dry method can save energy consumption of 2.34 × 1010 MJ per year and reduce pollutant emissions by 1.28 million tons per year. Compared with the wet modification process, dry modification features significant environmental advantages, high promotion value and broad application prospects.
