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 ,

. You will need to select a line

that defines the centerline of your road. If

one is not already created, refer to Page 41

for details on creating polylines and

alignments.

2. Tap the 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 button and

set up the backsight. Tap 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.
