摘要
全深式泡沫沥青冷再生技术能够实现废旧路面材料的全部就地循环利用,近年来在公路养护行业得到广泛应用,但当前尚缺少关于该技术的环境及经济效益定量分析。通过计算不同路面结构层的能耗及有害气体排放量,量化分析了全深式泡沫沥青冷再生技术的环境效益;通过全深式泡沫沥青冷再生技术与传统维修方法的造价对比分析,量化分析了该技术的经济效益。
The full depth foam asphalt cold recycling technology can realize the full on-site recycling of waste pavement materials,which has been widely used in the highway maintenance industry in recent years,but there is still a lack of quantitative analysis on the environmental and economic benefits of this technology.By calculating the energy consumption and harmful gas emissions of different pavement structure layers,this paper quantita⁃tively analyzes the environmental benefits of full depth foam asphalt cold recycling technology;by comparing the cost of full depth foam asphalt cold recycling technology with that of traditional maintenance methods,the economic benefits of this technology are quantitatively analyzed.
