In order to calculate surfaces and volumes, MDT can consider roadbed reinforcements. It is necessary that the initial and final vertices of the sections of the cross-section file to be reinforced are coded as Pavement, so that the program can automatically differentiate the part of each profile that should be reinforced. See the Cross-Section Configuration section for further details or the Obtain Cross-Section Profiles command.

          Below is a description of each parameter that defines the reinforcement application.

Apply: If this box is checked it indicates that we wish to apply reinforcement.

Tolerances: To apply reinforcement in a particular station the following condition must be met. The height difference in the vertices where the reinforcement is to be applied between the vertical alignment height and the terrain height must be between the “Minimum Dif.” and “Maximum Dif.” values.

          The objective of these tolerances is to control the application of reinforcement only when the terrain is very near the vertical alignment height.

Mode of application: Once it is decided to apply reinforcement to the template, in the area to be reinforced there are two options for the construction of the reinforcement base:

Thickness: Indicate here the thickness of the terrain in the area to be reinforced.

Adapt to Terrain: In this case a particular thickness is not applied to the reinforcement area, the subgrade is automatically adapted to the natural terrain of the area to be reinforced.

Designate Polylines: For the case that in top view the polylines indicate the reinforcement areas, selecting this button then said polylines, will automatically insert the reinforcement in the corresponding stations according to the definition specified.
