透水性路面与普通路面的生命周期评价

Evaluation on the life cycle of permeable pavement and common pavement

采用投入产出—生命周期模型(IO-LCA),分析了透水性路面建设的应用意义。通过计算透水性路面建设过程中的能耗和温室气体排放量,并与普通路面进行比较,发现透水性路面会多产生一定的能耗和温室气体排放;此外,利用透水性路面收集的雨水量数据,进一步分析了透水性路面建设的环境效益。结果表明,透水性路面将会长时间持续性地产生环境和社会效益,具有良好的应用前景。

Using the IO-LCA Model,this essay analyzes the significance of the water permeability road construction.By calculating the energy consumption and greenhouse gas emissions of permeable pavement in the construction process,and comparing with ordinary pavement,the results show that the permeable pavement will produce a certain energy consumption and greenhouse gas emissions; In addition,based on the rain water data collected by the permeable pavement,the environmental benefits of the construction of the permeable pavement are analyzed. It is found that the water permeable pavement will produce environmental and social benefits for a long time,and its application prospects are good.
