Modifying a Roadway Slope

There are several methods that you can use to create match slopes for

the cross sections. For each section, you can apply different cut and fill

slope conditions to the left and right sides. You can apply simple

slopes that follow a linear slope projection (3:1 in cut and 4:1 in fill).

You can also specify the use of benching for areas of substantial cut

of fill.

There are also more advanced slope calculation methods which vary

the design slope based on conditions such as the surface material that

you are cutting into and depth of cut/fill. When using these more

advanced options, applying slope control to cross sections is a two-

step process. First you set up the slope table(s) with the slope values

you want to use. The following illustration shows the Depth Control

Editor, which you can use to set up depth slope values.

After you set up the slope table(s), you apply these values to the cross

sections using the Edit Design Control command.
