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.


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

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

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.

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:

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.

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'.
