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 already created, refer to Page
44 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.
5. Enter the horizontal width of the left and
right sides of the road in the 1/2 Road Width
fields. These widths do not have to be the
same.
6. Enter the cross-slopes of each side of the
road in the X-Slope (%) fields.
Note: A negative X-Slope value will result in a
slope where water runs from the centerline of
the road toward the edge.
7. If the road profile also includes a curb or a ditch, check the Stake
Curb / Ditch
checkbox and define the curb or ditch as follows.
