摘　　要：将沥青混凝土路面建设期划分为原材料生产、原材料运输及施工三个阶段,建立能耗与排放模型,并利用编制的计算软件,详细分析计算了我国典型的半刚性基层沥青混凝土路面的建设期能耗与碳排放组成,并量化对比分析了三种节能减排技术和材料。结果表明：原材料生产、原材料运输及施工三个阶段的能耗占比为65%、8%和21%,碳排放占比为77%、5%和18%;计算得到各路面材料单位体积的建设期能耗与碳排放,可用于快速估算沥青混凝土路面能耗与碳排放;温拌技术对能耗与碳排放降幅分为7.5%~8.6%和6.7%~8%,再生技术能耗与碳排放降幅分为9.3%和10%,两种技术同时使用时其节能减排效应可以叠加,脱硫石膏水稳碎石对能耗与碳排放降幅分为9.6%和25.5%。与国外相比,我国沥青混凝土路面能耗与碳排放较高的主要原因在于水泥稳定碎石基层。Calculation models and software program of asphalt pavement energy consumption and emission are set up to analyze and calculate the semi-rigid base asphalt pavement energy consumption and CO2 emission generated in construction period which is divided into raw material production, transportation and construction phases. Three types of pavement technique and materials are compared with normal technique, and the result shows that： the energy consumption rate at raw material production, transportation and construction three phases is respectively 65%, 8% and 21%, with CO2 emission rate 77%, 5% and 18% accordingly. Unit volume pavement material energy consumption and CO2 emission are given to estimate energy consumption and emission of asphalt pavement efficiently. Warm-mixing technique can reduce energy consumption by about 7.5%-8.6% and COz emission by about 6.7%-8% recycle technique can cut down energy consumption by about 9. 3% and CO2 emission by 10% ;and Gypsum desulfurizer cement treated gravel can reduce energy consumption by about 9.6% and CO2 emission by about 25.5 %. Application of cement in the asphalt pavement is the right reason why our energy consumption and emission are higher than that of other countries.
