Slopes

Cut Slope %

The slope angle here is used to determine the cut slope angle when the template angle is set to AUTO (see Templates for more information)

Fill Slope %

The slope angle here is used to determine the fill slope angle when the template angle is set to AUTO (see Templates and Assign Fill Types for more information)

Expansion Factors

Cut Expansion Factor

Cut volumes are determined from the area of cut shown on the cross section. This volume is multiplied by the Cut Expansion Factor (for the appropriate ground types) before it is reported.

Fill Expansion Factor

Fill volumes are directly determined from the area shown on the cross section. This volume is multiplied by the Fill Expansion Factor (for the appropriate fill type) before it is reported.

File

It is possible to have several different sets of ground types (codes, factors etc.). These tables are saved in files with extension *.GND. When a traverse is created the default ground type table ROADENG.GND is loaded and "attached" to it. When a new terrain is opened the default ground type table ROADENG.GND is loaded and get saved with the design

Open Button

It is possible to load other tables using the Open button. When a traverse is saved the ground type information is saved with the traverse. This information is private to the traverse and will not effect other traverses. A terrain file does not hold ground type information. This information gets saved with the design if a terrain is used. 

Save Button

It is possible to modify and save new ground type tables. You can name these tables as you wish. To change the default ground type table save you changes in file ROADENG.GND.

NOTE:   The default Ground Types that came with the installation are not definitive and may not apply to ground conditions at your site. Use the editing features of this function to create Ground Types which will be meaningful at your location
