Basic Elements for Road Stake and Check Measurements
Description
In general there are four different basic stake out and check elements:
• Stringlines, for example, a centre line.
• Cross slopes or X-slopes, for example, the final carriage way.
• Slopes, for example, the end-slopes of a cross section.
• Surfaces, for example, a DTM surface.
Every stake out or check is based on one or more of these four base elements. For example,
a road crown consists of two X-slopes with one common stringline.
Stringlines
The stake out of a stringline is used in different situations:
• Centre line of a road.
• Edges of a road or any other change in slope.
• Gutters.
• Pipelines, cables and any other alignment related design feature.
