For the meet local traffic requirements was, should be designed a meet their own needs highway. Of this section highway design for the a cement concrete pavement structure, design of the main contents are: graphic design, vertical alignment design, crosssectional design, subgrade pavement design。 of which the roadbed design includes: roadbed width of design, subgrade cross sectional in the form designs. Design results there are floor plan, longitudinal section view, crosssectional chart, straight curve corner List of, roadbed design table, earth and stone calculation table, pavement structure diagram, pavement seams structural map and so on. To solve The main problem there is a reasonable Select a route with the select the optimal39。s pavement structure way of.
