45.3.7 Measuring Road Crowns
Graphical overview
Description • Staking road crowns allows the stake out of two cross slopes at the same time. If Toggle
offsets left/right is checked, the reference for ∆ offset is automatically switched between
the right and left cross slope depending on whether the measured position is to the right
or left of the middle stringline.
• When checking road crowns, it allows the check of two cross slopes at the same time.
The information for both cross slopes is shown at the same time.
Roads - Stakeout Roads - As built check
a) Position to stake out, in this case the left
stringline of the crown
b) Middle stringline of the crown, in this case
also the centreline
c) Left cross slope to stake out
d) Right cross slope to stake out
e) CL offset
f) ∆ offset
g) ∆ ht left
h) ∆ ht right
a) Left stringline of the crown
b) Middle stringline of the crown, common
for both cross slopes
c) Left cross slope to check
d) Right cross slope to check
e) CL offset
f) ∆ offset
g) ∆ ht left
h) ∆ ht right
