基于生命周期分析法的钢桥面铺装层环境影响研究
Investigation of the environmental impacts of steel deck pavement based on life cycle assessment
摘要
Abstract
To investigate the environmental impacts of steel deck pavement through the whole life cycle,the steel deck pavement was divided into five stages: raw materials production,asphalt mixture mixing,pavement construction,operation management,and pavement removing stage.Based on the process-based life cycle assessment (PLCA) method,the calculation methods of energy consumption and gas emissions of two typical steel deck pavement systems (EA +EA pavement and GA + SMA pavement) were determined.The data lists of two pavements were analyzed,and the calculation model was built.Four characteristic indices including primary energy demand (PED),global warming potential(GWP),acidification potential(AP) and respiratory inorganics (RI) were used to quantify the environmental impacts of two pavements.The results show that the environmental impact of the GA + SMA pavement is more than 1.3 times that of the EA + EA pavement.Moreover,the critical stage of energy-saving and emission-reduction of EA +EA pavement and GA + SMA pavement are the raw material production stage and asphalt mixture mixing stage,respectively.关键词
