Has carried on the analysis to the volume of traffic， search corresponding technical specifications， highway to determine the levels of need and the design of the parameters . Carries on the route selection in the horizontal plan， the ratio having carried out a scheme39。s elects and , ascertain out the optimum scheme,the line font having carried out a flat surface on road route designs that, the route relaxes the curve place interposing a are three vertical curves in this Profile Design. And the part has been satisfied even if the tie facing various call for in line font bination design. Has determined the cross section position and various elements in Cross section design and draws up the cross section chart. The roadbed design of basic content is determining roadbed side slope form and slope. Asphalt Pavement Design using cement concrete pavement , the main structure is to determine the thickness dimension. While on the road for drainage design to ensure road safety and the smoothness of the operation. Bridge design is a major part of its plane, profile and crosssectional design. This design not only to understand the various roadbuilding steps， and tempered their practical engineering solutions, also learned to play a solid knowledge and flexibility in the use of the role.
