Use these subassemblies to add overlay and tripping to road assemblies.
| Image | Subassembly | Common Uses |
|---|---|---|
 |
OverlayBrokenBackBetweenEdges: Creates a four-lane crowned overlay between existing gutter flange points on either side. Default Tool Palette: Rehab Subassemblies |
Overlay of four-lane road |
 |
OverlayBrokenBackOverGutters: Similar to OverlayBrokenBackBetweenEdges except that the overlay extends over the gutter to the curb flowline on each side. Default Tool Palette: Rehab Subassemblies |
Overlay of four-lane road |
 |
OverlayCrownBetweenEdges: Creates a crowned road surface between two existing edges of pavement. Default Tool Palette: Rehab Subassemblies |
Resurfacing a road with poor crown definition |
 |
OverlayMedianAsymmetrical: Widens a divided highway by extending the travel lanes inward along their existing cross slopes. An asymmetrical barrier is provided that resolves the elevation difference caused by extending the slopes inward. Default Tool Palette: Rehab Subassemblies |
Widening a divided highway to the inside |
 |
OverlayMedianSymmetrical: Similar to OverlayMedianAsymmetrical except that the cross slopes are adjusted so that the extend lanes meet at the centerline. Default Tool Palette: Rehab Subassemblies |
Widening a divided highway to the inside |
 |
OverlayMillAndLevel1: Provides milling or leveling as needed, which is then topped with an overlay of user-specified depth. The overlay slope can be set to match existing, set to match superelevation, or entered manually. Default Tool Palette: Rehab Subassemblies |
Single lane pavement overlay (not crowned) |
 |
OverlayMillAndLevel2: Similar to OverlayMillAndLevel1 except that it is intended for a crowned roadway. Rather than a single overlay slope, two slopes define the crown of the road. Default Tool Palette: Rehab Subassemblies |
Two-lane pavement overlay (crowned) |
 |
OverlayParabolic: Creates a parabolic overlay between two existing pavement edges. Default Tool Palette: Rehab Subassemblies |
Overlay of urban road |
 |
OverlayWidenFromCurb: Similar to OverlayWidenMatchSlope1 except that it extends inward from a curb flange. Default Tool Palette: Rehab Subassemblies |
Overlay and widen from curb inward |
 |
OverlayWidenMatchSlope1: Overlays the existing road, then provides widening at a cross slope that matches the existing road. Default Tool Palette: Rehab Subassemblies |
Overlay and widen on one side |
 |
OverlayWidenMatchSlope2: Similar to OverlayWidenMatchSlope1 except that it widens on two sides. Default Tool Palette: Rehab Subassemblies |
Overlay and widen on both sides |
 |
OverlayWidenWithSuper1: Similar to OverlayWidenMatchSlope1 except that the cross slope is set according to superelevation. Default Tool Palette: Rehab Subassemblies |
Overlay and widen with superelevation |
 |
StrippingPavement: Strips pavement to a given depth starting at the attachment point and working inward to the baseline. Default Tool Palette: Daylight Subassemblies |
Pavement removal |
 |
StrippingTopSoil: Strips topsoil to a given depth from the attachment point to a given stripping width. Default Tool Palette: Daylight Subassemblies |
Topsoil removal |
