•
Surfaces such as the final carriage way, are often staked/checked using
surface grades. A surface grade consists of a combination of two lines.
•
Refer to "43.6.3 Road - Basic Elements for Stake and Check Measure-
ments" for information on the usage of surface grades.
A 3D design of the road is required.

•
Surfaces, such as the end slopes of a cut or fill, are staked/checked using
slope methods.
•
Slopes are defined by two lines. Refer to "43.6.3 Road - Basic Elements
for Stake and Check Measurements".
•
When staking slopes, the point of interest is the intersection of the
defined slope with the natural surface (= catch point). Refer to "45.2.3
Advanced Slope Settings" for information on the slope staking methods
supported.
•
When checking slopes, the slope check is independent of the slope
method selected.
