摘　　要：以河北省某干线公路改建工程为研究对象,提出了一种基于生命周期评价的沥青路面建设各阶段能耗调研方法。通过对沥青路面实体工程建设进行系统调查,获取各阶段的资源消耗、能源使用及污染物排放数据,进行环境影响分析。研究结果表明,在沥青路面建设过程中,CO 2排放的环境负荷最为显著,其中原材料生产阶段和沥青混合料拌合阶段的贡献较大。沥青路面建设过程产生的环境影响主要包括温室效应、光化学烟雾和酸化效应等,其中温室效应的环境影响最大。此外,原材料生产阶段产生的环境影响最大,其次是拌合阶段。减少这些阶段的能耗和污染物排放将是降低沥青路面建设生命周期环境影响的关键措施。The study focuses on the reconstruction project of an arterial highway in Hebei Province,and proposes a method for investigating energy consumption at each stage of asphalt pavement construction based on life cycle assessment.By conducting a systematic investigation of the asphalt pavement construction project,data on resource consumption,energy usage,and pollutant emissions at each stage will be obtained for environmental impact analysis.The results show that CO 2 is the most significant pollutant emitted during the construction of asphalt pavement,with the raw material production stage and the asphalt mixture mixing stage contributing the most.The primary environmental impacts associated with asphalt pavement construction are GWP,POCP,and AP,with the GWP occupying the largest share of the total environmental impact.Additionally,the raw material production stage has the largest environmental impact,followed by the mixing stage.Reducing energy consumption and pollutant emissions in these stages will be key to minimizing the environmental impact across the entire life cycle of asphalt pavement construction.
