The expressway is 1.2 kilometres from K53+200 to K54+400, the designed speed limit is 80 km/h, and the wide of the subgrade is 34.5m with six lanes of two ways. The design basis are the lasted technical standards design and construction code, At the same time , some related information are also refere My prime contents of the design project include: the design of vertical section and cross-section, stability analysis of road foundation, side slope protection, retaining wall design, drainage design for subgrade and pavement, pavement structure design, ect. In this design, the subgrade slopes are pretected with grass planted in the framework; retaining walls used the batterly retaining wall; the size of drainage ditch is determined through by hydrological calculation in drainage design; each there structure of cement and alsphat pavement are developed distingsishly under the wet and dry conditions, the optimal pavement structure is obtained in terms of careful comparison; In this set of three cover sections of culvert for drainage, a cover for tractor access channel;and set up one bridges to reduce the occupation of houses and farmland.
