Analysis on Key Design Point of Pavement Structure and Subgrade of Municipal Road
In order to improve the design quality of mu-nicipal roads,this paper takes a main road as the research object,analyzes the design requirements of pavement structure and the selection methods of materials such as surface course,base course and bed course,and checks the surface deflection and bottom tensile stress of asphalt pavement based on URPDS2012 software.At the same time,the key points of subgrade design are discussed from the aspects of subgrade compaction,slope protection and soft soil foundation treatment.The research results can provide reference for similar municipal road design.
