摘　　要：为比较沥青路面和水泥混凝土路面的环境影响效应,基于全生命周期分析方法,对柔性基层沥青路面和连续配筋混凝土路面这两种重载路面的能源消耗、废气排放和路面材料再生等进行了对比分析.结果表明柔性基层沥青路面能源消耗和碳排放均远优于连续配筋混凝土路面,与不配筋混凝土路面相比,柔性基层沥青路面仍在碳排放方面具有优势,此外沥青路面的再生利用率更高.因此,基于环境角度考虑,沥青路面应在重载路面中得到更多的应用.In order to compare the environmental effects of asphalt pavement and concrete pavement,flexible base asphalt pavement and continuously reinforced concrete pavement(CRCP)were analyzed for the energy consumption,emissions as well as pavement materials recycling based on life cycle analysis.Flexible base asphalt pavement is far superior to CRCP in energy consumption and greenhouse gas emissions,and it is superior to concrete pavement without reinforcement in emissions.In addition,asphalt pavement also performs better in utilizing recycled pavement materials.Consequently,asphalt pavement should be recommended in heavy load pavement with the consideration of environmental protection.
