ABSTRACT
This design is about a road of second grad in the mountain area, Designing speed is 60km/h. It is a two-lane two-way road, no central separate belt. The design fully consider the terrain, geology, terrain, hydrology and
other natural conditions, according to the relevant specifications and design requirements of the task of highway, completed the design under the guidance of the teacher.
The design includes: plane, longitudinal section and cross section design. The plane linear design includes the data plane alignment, certain elements of horizontal curve calculation and the main points, widening pile number and coordinate; longitudinal section design including elevation, design elevation, the depth of cut to fill and vertical curve elements, fill and excavation height and roadbed side elevation calculation; cross-sectional design including the determination of standard section, draw each pile sections; the entire design process, in strict accordance with the relevant standards of the state. This manual mainly contents: horizontal alignment, horizontal alignment design, profile alignment design, horizontal and vertical alignment design, the cross-sectional design, the conclusion, thanks and main references.
Keywords: road grade, route selection, vertical design, horizontal design, cross-sectional design.
