Based on the information given by the analysis of the raw data， and the section of geology， topography， terrain， hydrology and other natural conditions， according to Highway Engineering Technical Standard， Road Design Standards issued by the Ministry of Communications and other related technologies indicators， I have finished this task under the teachers guidance. The area that this highway passes through belongs to plain with plain and hilly area. According to the traffic volume in the future， I design this highway into design speed of 100Km/h with bi-directional four-lane arterial highway， with route length of 5109.975 meters，Subgrade width of 26 meters， 3 horizontal curves， and 5 vertical curves. Line design including graphic design， longitudinal design and cross-sectional design; Then I accomplished the pavement drainage design， which uses ditches and drains for drainage to ensure the water stability of roadbed and pavement; at last， a composite design of pavement structure and other designs are also finished. The whole design have calculated the planar and vertical curve elements of this line， besides roadbed， pavement， bridges and so on. Complete the comprehensive design of the section of Nanning to Liuzhou arterial highway successfully.
