Create an Uncompacted PCS Surface
Create a surface for a paving control system (PCS), such as PCS400, that represents the ideal surface shape to be formed by a paver screed in placing asphaltic concrete by accounting for the compaction that occurs as the asphalt is rolled. This uncompacted PCS surface accommodates the differential thickness reduction that can occur as a result of variations in the laid mat thickness.
Prerequisites:
- See the Subscription Plans page. For a license matrix by command, see the License page in the TBC Community. Also see View and manage licensed features.
- Two surfaces
To access the command:
- Select Create Uncompacted PCS Surface in Surfaces > Create.
The Create Uncompacted PCS Surface command pane displays.
- In the Name box, type an identifier for the new surface as you want it to appear in the Project Explorer and Selection Explorer.
- In the Underlying surface list, select the surface that represents the base course on which the asphaltic concrete will be laid by the screed.
- In the Compacted material surface list, select the surface that represents the finished grade of the concrete.
- Type a value for the in the Rolling compaction factor box.
Expressed as a multiplication factor, this property states the compacted material's thickness as a multiplier of the laid material thickness prior to compaction. As an example, a rolling compaction factor of 0.75 results in a compacted in place mat thickness that is 75% of the thickness laid in forming the uncompacted PCS surface. That is, the material has shrunk by 25%. - Click OK. The uncompacted surface appears in the Project Explorer and graphic views.
- To see the new surface, use the 3D View.
Note: The uncompacted surface is dependent data; if you edit or delete either of the original surfaces, the uncompacted surface is also modified or deleted.
Note: Uncompacted PCS surfaces can be manually exported to GCS machines as .svd or .ttm files.
