Each component can have its own layerwork definition similar to the normal road layerworks with the attendant functionality:
You can use the Pavement Designer to define your component layerworks.
The component layers display with the road layers in the Cross Section Editor and cross-section plots.
You can calculate the volumes for component layers.
The example below shows how to define component layerworks.
Select Tools ► Component Editor from the Roads menu to display the Component Editor.
Load the "Side drains Concrete" feature file.
You are going to add layerworks to the "Type 1.1 v-drain EA" component. Select the Layerworks tab and note the following:
In the Formula column, you specify the region under which layers are placed.
As with roads layers, you specify a depth, description and shift value for each layer. Specify a negative shift value on the left side of the layer specification.
Right-click in the Formula column and select Define Region in the popup menu.
Click on both bottom lines of the v-drain to highlight them and right-click again.
The bottom face of the V drain is highlighted to show that the region has been defined.
Now, load any pavement design using the TRH 4 Pavements tool, by right-clicking in the Layer Description column.
The selected layerworks display in the Component Editor.
Change the option on the second row of the Formula column to Flat Layers.
Note that the first layer thickness is measured from the bottom of the lowest point of the defined region.
The component layerworks display along with the road layerworks in the cross-section.
