Road Layout

7. The

+ 0DS and 9 0DS tabs are used to view information about

the horizontal and vertical details of the road at the current
station. Tap the

6ORSHV tab to set up your slopes.

8. Four separate slopes can be defined for

situations requiring a cut or situations
requiring a fill, and can be different on
the right and left sides of the road. Fill in
the slopes that apply to your particular
job. (The fill slopes do not need to be
entered as negative values since Survey
Pro knows that these are negative
slopes.)

9. Tap

the

)LOO +LQJH 3RLQWV tab to define

where the hinge point will be computed

in areas that require a fill. Some people prefer to compute this
point somewhere other than the end of the last segment to
simplify the situation where a ditch meets an area requiring a fill,
which would otherwise result in an area with two similar or
identical negative slopes.

10. Use the

and !! buttons to select the segment where you

want to compute the hinge point in situations requiring a fill for
each side of the road. (The hinge point will be computed at the
end of the segment listed here.)

11. Tap the

6WDNH &3 ! button to continue to

the next screen where the catch points at
the current station can be located. This
screen is identical to the screens used in
the non-road layout slope staking routine.
If you are not familiar with these screens,
refer to Page 122.

12. Once the catch point is staked and stored,

you will return to the screen described
above where the station to stake can be
advanced by the station interval by

tapping the

1H[W 6WDWLRQ button and the process can be repeated

to stake the next catch points.
