摘　　要：灌入式复合路面作为一种新型路面养护技术,其经济与环境效益尚不明确。本研究基于实际工程,采用生命周期评价和生命周期成本分析,量化评估了灌入式复合路面的经济成本和环境影响,并与传统铣刨重铺进行了比较。采用热图可视化方法进一步探究了路面使用寿命对评价结果的影响,明确了其实现经济和环境优势所要达到的使用寿命要求。结果表明,灌入式复合路面相比铣刨重铺在材料生产和施工阶段的能耗、碳排放和综合造价分别高5.16%、58.10%和136%。考虑路面使用寿命后,灌入式复合路面只要能比铣刨重铺多服役一年以上,就具有能耗优势。若其使用寿命能进一步达到铣刨重铺的1.58倍以上,就能实现减碳作用。经济效益方面,由于灌入式复合路面的初期投入成本较高,仅当其使用寿命远高于铣刨重铺时,如灌入式复合路面服役14年,铣刨重铺仅服役5年,才能具有经济优势。As a new pavement maintenance technology,the economic and environmental benefits of the permeable composite pavement are not yet clear.Based on a practical maintenance project,this study carried out a quantitative evaluation of the economic costs and environmental impacts of permeable composite pavements using life cycle assessment and life cycle cost analysis,and compared it with traditional mill and fill.The results show that the energy consumption,carbon emissions,and overall cost of the permeable composite pavement compared to mill and fill were 5.16%,58.10%,and 136%higher in the material production and construction phases,respectively.After considering the pavement service life,as long as the permeable composite pavement can serve more than one year more than mill and fill,it will have an energy consumption advantage.If its service life can further reach more than 1.58 times that of mill and fill,carbon reduction can also be achieved.In terms of economic benefits,advan-tages can only be achieved when the service life of the permeable composite pavement is significantly longer than that of the mill and fill.For example,the permeable composite pavement has a service life of 14 years and the mill and fill only serves 5 years.
