摘　　要：受早期建设条件限制,山岭重丘区改扩建工程设计方案与既有道路偏差较大。为研究复杂工况下高速公路改扩建沥青路面的设计要点,文章总结了国内现有改扩建工程经验,分析了不同总体设计方案下路面设计的特点,着重阐述了既有路面结构状况评定、分车道设计、既有路面补强与拼宽设计、路面调平设计、铣刨料再生利用设计等多方面的关键技术。Due to the limitation of early construction conditions,the design scheme of reconstruction and expansion engineering in mountainous and hilly areas deviates greatly from the existing roads.In order to study the design points of asphalt pavement in expressway reconstruction and expansion under complex working conditions,this paper summarizes the experience of existing reconstruction and expansion engineering in China,analyzes the characteristics of pavement design under different overall design schemes,and focuses on existing pavement structure evaluation,lane division design,existing pavement reinforcement and widening design,pavement leveling design,milling material recycling design and other key technologies.
