Creating Finished Ground Cross Sections | 181
Modifying Roadway Slope
There are several methods that you can use to create match slopes for cross
sections. For each section, you can apply different cut and fill slope condi-
tions 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 use benching
for areas of substantial cut or fill.
More advanced slope calculation methods vary the design slope based on
conditions, such as the surface material that you are cutting into and the
depth of cut/fill. When you use these more advanced options, it is a two-step
process to apply slope control to cross sections. First, set up the slope tables
with slope values you want to using the Depth Control Editor.
Display the Slope Control dialog box, by using the Edit Design Control com-
mand.
After you set up the slope tables, apply these values to the cross sections using
the Edit Design Control command.
Key Concepts
■ Simple slopes have typical cut and fill slope values.
5 From the Cross Sections menu, choose Design
Control ➤ Edit Design Control to set up the design
control parameters and process the sections.
These parameters control the template you can use when
processing cross sections, ditch values, slope control
values, transitions, and superelevation.
Whenever you modify the design control parameters, the
cross sections are processed automatically.

6 You can view and modify individual cross sections by
selecting Cross Sections
➤ View/Edit Sections.
This is the recommended method for modifying
superelevation regions.
