How do you draw road cross section quickly and easily?

Answer 1

Think like making a cake. The bottom (road bed) is one color. Make a "U" type of "bed", then fill it up with the components of the road bed. Make the top of the road level with the "U" and there is a cross section sketch.

Answer 2

A road cross section diagram for an existing road is a view of the road construction ran to illustrate the various layers and construction details. There is no quick and easy way to draw such an illustration. You will need detailed construction information or, if this is not available. cores from a transverse section of the road. The cores will also provide composition data for the various layers of fill. You will also require measurements of the road to indicate width, crown height and associated structures such as drains ditches and medians,The actual drawing will require typical drafting tools, data converted to scale measurements etc.

A sketch to show intended construction can be done without details but should should still indicate rough measurements and composition of layers.
