Command Calculate New Profile calculates points for a new profile. New points are calculated by raising/lowering the entire roadway pavement.
Click on the Calculate New Profile icon.
Reconstruction dialog box opens. Here you can define the thicknesses of the wearing course, minimum and maximum of the base course.
The wearing course represents the uppermost layer of a pavement that comes in contact with traffic. It is typically placed on the base course.
You can view the existing terrain line while editing the thickness of resurfacing materials. Volumes of wearing course, base course, and milling are calculated automatically, so the user can define the optimal height of vertical alignment.
If you press the button 
, the Settings dialog box opens. Here you can define which parameters you want to see in the display window.
Check the Draw reconstruction points option and confirm with OK.
For a detailed description of the parameters see the Help file.
After the superelevations of an existing roadway have been calculated and the new ones designed, you have to define the elevation of the vertical alignment. Assuming the fact that you want to cover the roadway with asphalt of appropriate minimal thickness, it is necessary to determine the point that will, with respect to the calculated superelevations, increase the vertical alignment to the highest possible level.
There are two ways to design new vertical alignment: by points or by tangents between points. If points are used, then the user can create vertical alignment with BestFit functionality. There are also possibilities to take the limited terrain into account for reconstruction analysis.
In our case, we used to add vertical alignment to the profile by (reconstruction) points. You can see the result in the picture below.
