Research on Asphalt Pavement Design for Expressway Reconstruction and Expansion in Mountainous and Hilly Area
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.
