沥青路面建养碳排放与低碳路径综述OA

In existing research,the calculation of carbon emissions of asphalt pavement is mostly focused on a cer-tain stage of the life cycle,and there is no quantitative method for energy consumption and carbon emissions throughout the lifecycle of asphalt pavement that is suitable for the actual production situation in China.It is of prac-tical significance to summarize and analyze the carbon emissions during the construction and maintenance process of asphalt pavement in order to promote the achievement of the"dual carbon"goal in the transportation sector.A system-atic review was conducted on the current research status of carbon emissions throughout the entire lifecycle of as-phalt pavement construction and maintenance at home and abroad,as well as the carbon emissions situation.Start-ing from the main stages of carbon emissions generation,combined with low-carbon asphalt materials,low-carbon asphalt production processes,and low-carbon management measures,the low-carbon construction and mainte-nance path are summarized in this paper.And proposes future research directions that should be focused on,in or-der to to provide reference for the theoretical research and practical of low-carbon asphalt pavement construction and maintenance projects in future.
