【摘要】：针对高速公路沥青路面生命周期中存在的高能耗、温室气体排放等环境问题,为确定其主要的环境影响类型及影响阶段,对广东省某高速公路沥青路面开展了生命周期环境影响评价。确定其生命周期范围为建材准备阶段、施工阶段、运行阶段、拆除阶段及垃圾处理阶段,完成了生命周期的LCA建模分析,得到项目数据清单;以ADP、AP、EP、GWP、HTP、POCP为评价类别,应用CMLCA软件进行评价。结果表明:(1)高速公路沥青路面环境影响最大的阶段是运行阶段,贡献率为88.88%,其次是准备阶段,贡献率为8.50%;(2)ADP、AP、EP、GWP、HTP、POCP影响主要集中在运行阶段,贡献率均超过80%;(3)主要的环境影响类型是HTP和ADP,贡献率分别为47.02%、36.05%。
[Abstract]:In view of the high energy consumption, greenhouse gas emission and other environmental problems existing in the life cycle of asphalt pavement of expressway, the main types and stages of its environmental impact are determined. The life cycle environmental impact assessment of a expressway asphalt pavement in Guangdong Province was carried out. The life cycle is defined as building material preparation stage, construction stage, operation stage, demolition stage and garbage disposal phase. The LCA modeling analysis of the life cycle is completed and the project data list is obtained. Taking ADP,AP,EP,GWP,HTP,POCP as the evaluation category, the CMLCA software was used for the evaluation. The results show that: (1) the most important environmental impact stage of expressway asphalt pavement is the operation stage, the contribution rate is 88.88%, the second is the preparation stage, the contribution rate is 8.50%; (2) the contribution rate of ADP,AP,EP,GWP,HTP,POCP was over 80% in the operation stage, and (3) the contribution rate of HTP and ADP, were 47.02% and 36.05% respectively.
