The Slope Stake routine can automatically determine if the
outer slope of the road profile should have a positive or a
negative slope based on the location of the hinge point. If
the hinge point is located below the surface of the terrain,
a positive slope is selected and a cut will be required,
starting at the catch point. If the hinge point is located
above the surface of the terrain, a negative slope is selected
where a fill will be required, starting at the catch point.
The illustrations here show examples of a road that requires a fill on
both sides; a road that requires a cut on both sides; and a road that
requires a fill on one side and cut on the other side.
It is important to remember that when slope staking a road, the road
profile always remains the same and the slope of the final segment
can only equal the specified positive (cut) slope, or the specified
negative (fill) slope, but the length of this final segment can vary as
much as necessary until it ends at the surface of the terrain (the
catch point).
Defining the Road Cross-Section
1. From the Main Menu select . Stakeout ,
Slope Staking . You will need to select a line that
defines the centerline of your road. If one is not
available, refer to Page 49 for details on creating
polylines and alignments.
2. Tap the Tap Line button and then tap the polyline
or alignment that describes the centerline of the road
you want to slope stake and then tap to continue.
3. Enter the station that you want to assign to the
starting point of your alignment or polyline in the
Begin Station field.
4. If the backsight is not yet set up, tap the Backsight
button and set up the backsight. Tap Next to
continue.
