Abstract

Abstract

Under the background of the Dual Carbon goal of China, to achieve the recycling of steel slag and reduce the energy consumption and carbon emissions of the transportation industry, this paper took the waste steel slag of Pingxiang Steel Plant as the research object, designed the steel slag asphalt mixture AC-13 test group based on the characteristics of the waste steel slag, and conducted road performance tests under various environmental conditions, and compared it with the diabase asphalt mixture AC-13 control group. Based on the life cycle analysis (LCA), the article analyzed its energy consumption and CO₂ emissions. The results showed that the steel slag asphalt mixture had better road performance under all tested environmental conditions than the diabase asphalt mixture, and its energy consumption and CO₂ emissions were effectively reduced, which proved the steel slag asphalt mixture a sustainable cleaner pavement material.
