ABSTRACT According to the design plan, the design issues for a highway, lots are plain with micro hill area。 The route location in an area of Zhenjiang City, the city is relatively flat。 The starting point of design section is K003 020, K005 60 is the end of the whole length of 2040m, the design of two-way four Lane Road, central a median line design speed kilometers per hour, is commonly used in pavement design oasphalt concrete pavement。
This design is mainly pided into three parts。 In design of plane line selection, then the horizontal and vertical section and pavement structure design, finally the drainage design, culvert design and earthwork calculation。
The main content the road route design: determine the line line, line selection after the plane design; longitudinal design cross-sectional design; there is the design of subgrade and pavement drainage and necessary culvert design。 A part of the design related design sketch。 All that is required to calculate the elements of horizontal curve and vertical curve calculation; earthwork calculation。
