ABSTRACT 

This design studies the suhu highway which covers K138+150-K140+620, including: graphic design, alignment design, cross-sectional design, roadbed design, retaining wall design, road drainage as well as protective engineering and pavement structure design. The design is in strict accordance with the code standard and consults related references. The factors of topography, geology, safety, environmental protection, land use, construction condition and economics were taken into consideration in linear design; in the alignment design, according to the road grade, natural conditions and control elevation of structure, the design determines the appropriate elevation, the longitudinal slope and slope length of each slope section, and designs vertical curve; in the part of cross-sectional design, the design considers highway grade, driving requirements, natural geological condition, the construction method, and local farmland construction in order to guarantee the stability of roadbed and drainage. In the roadbed design part we should select reasonable embankment packing and compacted standards; in the part of retaining wall design, the designer uses a gravity retaining wall and sloping base and the economy and safety of retaining wall are taken in account; in the design of highway drainage and protective engineering, in view of the factors of local geology condition, landscaping, landscape improvement and relieving of visual fatigue of drivers, the design uses grass sod as well as facing wall of window-type to protect part of the side slope; in the part of pavement structure design, according to the design requirements and local conditions, the design selects bituminous concrete pavement. 

Keywords: flat freely design; subgrade design; pavement design
