And then put forward the specification documents needed in design, including the selection of standard; graphic design requirements; longitudinal section design requirements; cross-sectional design, subgrade and pavement design requirements and some other specification. This design is the design of Lin Jia Gou to Ma Jia Gou Cun secondary road project. The design content mainly includes graphic design course; vertical section design; design of subgrade and pavement; retaining wall structure and cross section slit blocking protection engineering design of wall expansion, finally to slope protection, side ditch drainage and protection facilities to protect the road in accordance with the relevant specification design. Method is to calculate the traffic volume; calculation of horizontal curve and transition curve; calculation of longitudinal section design; cross-sectional calculation; calculation of subgrade and pavement structure; finally is to calculate the retaining wall stability and calculation of earthwork volume.
