【摘要】：分析了三种高速公路沥青混凝土路面和两种水泥混凝土路面的原材料获取和施工能耗。研究结果表明,水泥混凝土路面的原材料物化能耗高于沥青混凝土路面。半刚性基层沥青混凝土路面和水泥混凝土路面的原材料物化能耗中水泥贡献比例最高。全厚式沥青混凝土路面的原材料物化能耗中沥青贡献比例最高。沥青混凝土路面施工阶段能耗远高于水泥混凝土路面,其中全厚式沥青混凝土路面施工阶段能耗最高。沥青混凝土路面施工能耗主要发生在拌和阶段,水泥混凝土路面施工能耗主要发生在摊铺成型阶段。综合考虑材料物化阶段和施工阶段总能耗,两种路面结构类型都是原材料物化阶段能耗占非常显著的比例,特别是水泥混凝土路面,该比例高达95%左右。
[Abstract]:The raw material acquisition and construction energy consumption of three kinds of highway asphalt concrete pavement and two kinds of cement concrete pavement are analyzed. The physical and chemical energy consumption of raw materials of cement concrete pavement is higher than that of asphalt concrete pavement. The contribution of cement to physical and chemical energy consumption of raw material of semi-rigid base asphalt concrete pavement and cement concrete pavement is the highest. Asphalt contributes the highest proportion of the physical and chemical energy consumption of the raw materials of the soil pavement, and the energy consumption of the asphalt concrete pavement is much higher than that of the cement concrete pavement during the construction phase. The energy consumption of full thickness asphalt concrete pavement is the highest in the construction stage, and the energy consumption of asphalt concrete pavement construction mainly occurs in the mixing stage. The construction energy consumption of cement concrete pavement mainly occurs in the spreading and forming stage. Considering the total energy consumption in the material physicochemical stage and the construction stage, the energy consumption of the two kinds of pavement structures is very significant in the physical and chemical stage of raw materials. In particular, cement concrete pavement, the proportion of up to 95%.
