of Huang Song Dian to Dun Hua
(K136+500-K138+600)
ABSTRACT
This design is from the Central Plains to the transition region of Jilin Province in
eastern mountain area(Department of the Chinese second uplift)two highway construction drawing design.The first step is to route design,including:Graphic Design(design and calculation of horizontal curve),vertical section design(design and calculation of vertical curve),cross-sectional design(design roadbed width,side ditch,ditch lane,etc.),the design result swith plan,vertical section,transverse plane figure,straight curve angle table,table,design of the Subgrade Earthwork Calculation Table;the second step is the design of roadbed and road surface,wherein the roadbed design includes:width of road bed design,subgrade cross section design.Pavement with asphalt pavement,the design results include: the pavement structure design,the standard axle load conversion,design calculation,each layer of material allowable bending stress calculation,bending stress checking,design results of pavement structure,axle load conversion table.
