基于路面寿命周期理论，将沥青路面养护工程碳排放分为原材料生产、原材料运输和养护施工三个阶段，并提出三个阶段的碳排放计算方法；计算了三种罩面养护技术和三种大中修养护技术的CO2排放量与排放强度。通过对比分析发现：在罩面养护技术中，同步碎石封层技术的CO2排放量和排放强度都最小；在大中修养护技术中，就地热再生的CO2排放量最小，厂拌热再生的CO2排放强度最小。

Based on the life cycle theory of pavement, the carbon emissions of maintenance engineering of asphalt pavement were divided into three stages:production and transportation of raw materials and con?struction. And also the calculation method of carbon emission was proposed for above three stages. The quality and intensity of CO2 emission of three overlay conservation techniques and three repairing tech?niques were calculated out. It was found that the synchronous surface technology has smallest quality and intensity of CO2 emissions among the three overlay conservation techniques. And the hot recycling in-place has smallest quality of CO2 emission and the hot recycling in central plant has the smallest intensity of CO2 emission.
