Pavement

The Pavement dialog can be started from:

MOUS_ICO Novapoint > Road task > Design > Pavement

MOUS_ICO Cross-section Viewer > Right-click a pavement layer

MOUS_ICO Road Modeler > Data > Road Pavement

Under the road surfaces, the pavement layers must be defined.

The pavement can be handled in different ways, and the dialog is divided into some individual tabs:

Pavement | Inner slope | Gradual layers | Rehabilitation | Median | Layer Properties

It is also possible to do a Detailed Pavement description if needed.

Procedure

Following are the key steps for pavement description using this function:

1. Define a Pavement Template.

2. Select the template and describe the pavement in the lower table of the Pavement dialog with up to 10 different layers.

   • Repeat steps 1 and 2 to create and define as many templates as necessary.

3. Define the stations and templates to use for soil cut and fill and rock cut.

   • A gap in the stations will create an interpolation between the used templates for the given stations

4. Define the Inner slope.

5. Define the Gradual layers if needed.

6. Define the Rehabilitation and Median tabs if needed.

7. Detail the Layer Properties with the layer materialtype and detailed descriptions of the material.

Note: Ensure that the correct pavement template is active before describing/modifying the pavement.

Tip: With the Cross-section Viewer, open and modifying/describing the pavement description and using Apply shows changes immediately for the open cross-section.

The Dialog

The Dialog Box is divided into different panes. The top half of the dialog is static, while the bottom half changes according to the chosen tab. For documentation on the tabs, please see the links at the top of this documentation page.

For a walk-through of the procedure, see the Procedure above.

Pavement templates

The leftmost pane lists the pavement templates. To apply any kind of pavement to the road model, at least one pavement template must be created. Select the appropriate template and define the layer thickness in the pavement, inner slope, gradual layers, rehabilitation, and median.

Note: Ensure that the correct template is active before describing/modifying the pavement.

Make a duplicate of a template

1. Copy & Paste

   • Copy a template by right-clicking and selecting Copy or pressing Control + C on the keyboard.

   • Paste a template by right-clicking in an empty template cell and selecting Paste or pressing Control + V on the keyboard.

2. Drag & Drop

   • Select a template

   • Hover over the lower right corner of the template until a + is showing

   • Select the + and drag down one or more cells.

Edit a template

See Pavement.

Rename a template by selecting the template name.

To Insert a row, select the template, right-click and select Insert row. This will also copy the selected template.

Move the pavement templates up or down on the list with the arrow buttons.

Apply a Template to Sections

When the templates are defined it is possible to specify the sections for them to be valid in the Soil cut and fill and Rock cut pane.

Define the first and last chainages and select the template from the pull-down menu of the column Template.

• Define the sections related to the soil formation and fill in the table Soil cut and fill.

• Define the sections related to the rock formation in the table Rock cut.

• Pavement is described with templates so that if the designer is switching between multiple pavements, each instance is described only once.

• A gap/break in the sections will create a longitudinal wedge. The difference between the templates will be interpolated.

Soil/Rock usage

The pavement type (sub-grade type) is detected during the cross-section calculation and automatically assigns the respective pavement type (Soil-pavement/Rock-pavement).

Using this button opens the Road Pavement Type dialog where it is possible to change the proposed road pavement types. The following sub-grade conditions can occur:

1. Soil

2. Rock

3. Soil and rock

4. Soil and Fill

5. Rock and Fill

6. Soil and rock, Fill

7. Fill

The standard condition is that the program will propose a rock type when the cross-section is a pure rock cut (condition 2 above). For all other conditions, a soil type will be used.

• When successive cross-sections have the same sub-grade they are represented by just one row in the list.

• The pavement type can be modified using the column Pavement.

• Click in the column to switch between the pavement types.

• The grey cells cannot be edited.

• A new section can be inserted using the button Insert. Select a row and use the button.

• Use the Delete button to delete selected sections. Rows with grey cells cannot be deleted.

• Use the Reset button to delete all the information regarding the subgrade type. To update the list please do a new road model calculation. This may be useful if there have been changes to the terrain model, road model, or sub-surface layer information or to build the list from scratch.

Insert Edge

For Insert Edge with leftwards/rightwards slope, see Insert Edge in Pavement.

When changes have been done to the road pavement description press Apply or OK to save the changes.

Calculate the road model to update the resulting model.

Display Properties

NOTE: Available on Road tasks version 2.1 and above.

The Display Properties refers to how to show the Layer Properties in the dialog. By default it will be set to 'Partial'.

• None - All information related to Layer Properties are hidden from the user to minimize the dialog.

• Partial - All road surfaces that has edits in the Layer Properties will show the content of the rows with Layer Properties information

• All - All road surfaces are shown with the rows for Layer Properties.
