摘要
再生沥青混合料在道路工程应用中展现出良好的路用性能和环保效益.研究发现,再生沥青混合料的高温稳定性、水稳定性和抗疲劳性能均满足使用要求.生命周期评估表明,再生沥青混合料在材料获取、生产、施工和使用阶段具有资源节约和温室气体减排优势,但仍需警惕再生料的重金属污染风险.通过环境效益的定量分析和情景比较,可以权衡环境与经济效益,优化工程决策.
Abstract
Recycled asphalt mixture has shown good road performance and environmental benefits in road engineering applications.It is found that the high temperature stability,water stability and fatigue resistance of the recycled asphalt mixture meet the requirements of use.The life cycle assessment shows that recycled asphalt mixture has the advantages of resource saving and greenhouse gas emission reduction in the material acquisition,production,construction and use stages,but the risk of heavy metal pollution of recycled asphalt mixture still needs to be vigilant.Through quantitative analysis of environmental benefits and scenario comparison,environmental and economic benefits can be weighed and engineering decisions can be optimized.
