| Summary: | In the context of the dual carbon policy, environmental protection has become pressing need of the times. Polyester fiber asphalt mixture is gradually replacing traditional inefficient ordinary asphalt mixture due to its excellent performance. However, the production process of polyester fiber asphalt mixture involves a large number of chemical reagents and greenhouse gas emissions, seriously polluting the environment. At present, there is insufficient research on the environmental impact of polyester fiber asphalt mixtures. This article is mainly based on the research status of various properties of polyester fiber asphalt mixture and the effective recycling methods in the research. Through LCA life cycle assessment combined with ICCS evaluation method, the environmental impact is quantitatively analyzed from three indicators: fossil consumption, land use, and biological impact. The environmental benefits of 1kg polyester fiber and asphalt lifecycle were approximately calculated. Finally, based on this, a simple linear calculation model for the environmental impact of polyester fiber asphalt mixture was proposed. |
