摘　　要：沥青路面的再生利用是我国道路交通系统“固废利用”的重点项目之一。基于国内外沥青路面再生利用技术的发展现状,对其再生利用的技术条件及发展趋势进行了分析,文章提出了旧料油石配比和矿料级配的检测、含水量的控制、旧料挖切作业时的天候选择,以及挖切前路面的清理等直接影响到路面旧料再生质量、制备成本和环境保护等主要技术准备内容,并对这些项目所涉及的作业工艺及主要技术参数的选择进行了分析和量化,对相应的工程应用效果和前景进行了分析和展望。The recycling of asphalt pavement is one of the key projects of“solid waste utilization”in our country’s road traffic system. Based on the development status of asphalt pavement recycling technology at home and abroad,the technical conditions and development trend of its recycling are analyzed. The choice of weather during the excavation and cutting operation and the cleaning of the road surface before the excavation and cutting directly affect the main technical preparation contents such as the quality of the old pavement material regeneration,preparation cost and environmental protection,and the operation technology and main technical parameters involved in these projects. The selection is analyzed and quantified,and the corresponding engineering application effects and prospects are analyzed and prospected.
