The design speed is 100km/h.The width of the subgrade is 30 meters.The basic type of horizontal curve is adopted in this design for all the 4 horizontal curves and its minimum radius is 800m. Two vertical curves are designed and its minimum radius is 10000m and 10000m for convex vertical curve and concave vertical curve respectly.The minimum longitudinal grade is % which meet the drainage. All of the adopted technical standard can meet the highway with the second-class service level. 4 bridges are designed, which are medium bridge and small bridge respctively and 2 pipe culvert are also desinged.Different kind of drainage facilities are used in the drainage design. Gravity retaining wall and vegetation protection are used for the slope protection. The asphalt pavement is used in this highway. The concept of environmental protection is carried through in all the design to make the highway consistent with the nature. Different kinds of professional software are used to optimum the design result.
