In this paper, the sustainability of induced healing asphalt pavement is demonstrated by comparing the impact of asphalt pavement maintained by induced healing asphalt pavement technology and traditional maintenance methods (such as milling and overlaying). The functional unit selected is a 1-km lane with an analysis period of 20 years. The stages to be considered are material manufacturing, paving, maintenance, milling and demolition. Two case studies were analyzed to assess the impact of different technologies on the energy consumption and environmental performance of each maintenance alternative. By comparing the energy consumption and environmental emissions of the whole life cycle of pavement under the two technical conditions, the results show that the total energy consumption of traditional asphalt pavement is about 2.5 times that of induction-healed asphalt pavement, and the total greenhouse gas (GHG) emissions of the former are twice as much as that of the latter.
本文通过比较诱导修复沥青路面技术维护的沥青路面与传统维护方法(如铣刨和加铺)的影响,证明了诱导修复沥青路面的可持续性。选择的功能单元是一条1公里长的车道,分析期为20年。要考虑的阶段包括材料制造、铺设、维护、铣刨和拆除。分析了两个案例研究,以评估不同技术对每种维护方案的能源消耗和环境性能的影响。通过比较两种技术条件下路面全生命周期的能源消耗和环境排放,结果表明,传统沥青路面的总能源消耗约为诱导修复沥青路面的2.5倍,前者的温室气体(GHG)总排放量是后者的两倍。
