Ranges

Each source element, should have a list of ranges.

If there are no items sorted in the source material or demand, it can not be used in the distribution calculation. So much in the calculation of DMT.

Each Range item will have the following properties:

1. Name - Item name. For items of type Arbitrated, you can specify any name. For items of type Calculated, it is the DDM program that chooses the name, based on the Code of the source or demand and an incremental counter
2. Group - Item group. When the Group sources and demands option is checked, when you sort the areas and volumes, each ranked item will have a group. Note, source items can have the same group, for example first, second or third category cuts can be all grouped as Cut-XXX, where XXX is a numeric index. The same can be considered for the first, second or third category.
3. Type Type of item, can be:
   • Calculated - Are calculated by the program by clicking the sort
   • Arbitrated - When determined by the user. In the case of soft spot soils, sections are not evaluated to determine the volume, but rather evaluated by the area and depth of occurrence.
   The Classify has no effect on items Arbitrated
4. Start Raw Station - linear distance from the start of the alignment to the starting point of the item
5. Final Progress - linear distance from the beginning of the alignment to the end point of the item
6. Average Raw Station - Average center or mass station of the item. The DDM program uses the arithmetic mean weighted by the cross-sectional areas to get this value
7. CBR - California Support Index. calculated items have no value because they have already been sorted according to the target ranges that fit
8. Expansion Expansion of the soil. calculated items have no value because they have already been sorted according to the target ranges that fit
9. Geometric Volume - Accumulated geometric volume of the item. The items of type calculated use the cumulative values ??from the Volume column of the Areas and Volumes tab between the start and end steps
10. Distributed Volume - Volume that was actually distributed in the distribution tab. In the case of loans or deposits that should have type set to variableThis value must be less than or equal to the geometric volume. For those defined for type fixed, they should be the same, or the distribution will not be correct
11. Additional Distance - In the case of borrow pit or dump site (which are the cases where the source item is variable type), these may be outside the domain range from the project. Thus, it is mandatory to walk a distance to this item. Note: for the DMT calculation, you must be informed in which station will be the access point of the item, so the DMT between two items will be:
    DMT = ABS ([Average of Source] - [Average Raw Station of Demand]) +
    [Dead Distance of Source] + [Dead Distance of Destiny]
12. Start Station - Converted value of the initial progressive as a function of the parameters of station equations
13. End Station - Converted value of the final progressive as a function of the parameters of Stations equations
14. Average Station - Converted value of the average progressive as a function of Stations equations
15. Ranges - These are the possible demands for each item classified. For example, if we have a landfill body with a final layer, this will have higher CBR requirements than the landfill body. Thus, in the frame of DMTs, if a given source item does not contain the appropriate range for a demand, it means that its CBR is low, or even the expansion or permeability is high. So this movement should not be done

The Classify button can have one of the following states:

• Classified - When the button is pressed and the ranges are recalculated, the button looks like this, indicating that the items are updated
• Outdated - area or volume or even source and demand is changed, the button changes to this state indicating that the ranges are outdated

If any value is invalid, the text will be in red, indicating the error.

Background cells are editable. The others are read-only.

Caution!
When classifying items, or modifying any item in the ranges tab, the DMTs are automatically recalculated. Any edits to the DMT tab will be lost.

If any value is invalid, the text will be in red, indicating the error.

Cells with yellow background, are editable. Cells with white background, are read-only.
