 Abstract
 The design for the secondary highway design in Zhumadian to Zhengyang the k0 the +000- of
the K2 +145.64 designed this road length 2145.64m, a design speed of 80km / h. Were set up
across the board two transfer points, two point of gradient change. The main purpose of the
section road design is for the convenience of along the way residents travel and the transport of
goods, improve the level of economic development in the region.
 The main items to be addressed in the design: the graphic design of the road program
development, comparison and selection, route, longitudinal design, cross-sectional design,
interchange design, the design of embankment, subgrade drainage system design, pavement layer
design as well as part of related drawings and tables.
 On road routes in the detailed design of horizontal alignment design, refer to the horizontal
curve design principles and standards to determine the corner coordinates to calculate the elements
of the horizontal curve; longitudinal design with two vertical curves, and also to meet the Plane in
the linear combination of design, drawing longitudinal section; in the cross-sectional design to
determine the cross-sectional composition and various elements, cross-sectional diagram is drawn,
the standard cross-sectional diagram, and earthwork quantity calculation and allocation of ;
roadbed design is to determine the shape and slope of the embankment slope and roadbed drainage
design, drainage design to determine the shape and size of the ditches and drains; pavement design,
considering the many technical indicators to determine the road specific composition, structure,
and each layer of road material to draw the pavement structure diagram, the last budget the design
calculations, calculate the total project cost, but also gives the part table and drawi ng.
