road monitoring 2020

Road monitoring
- determination of the thickness of pavement layers;
identification of subsidence and flooded areas;
- monitoring the condition of the road pavement.

THE RESULT OF INTERPRETATION IN THE ANALYSIS PROGRAM 7
:
allows you to mark the places of high humidity on the radarogram. Moisture analysis can be performed simultaneously for several channels (interpretation of sounding results by several antenna units).
The analysis results are displayed in the lower part of the radarogram in the form of colored bars.
