This palette lets you assign lane inputs and properties to a rehab corridor, edit the rehab input parameters in the properties table, and apply your modifications to the selected rehab corridor region .
If you are creating a new rehab corridor, once you apply your rehab parameters to your rehab corridor,
Autodesk Civil 3D will automatically build the assembly for your rehab corridor, and will automatically assign the appropriate rehab and/or cross slope optimization subassemblies to your rehab corridor regions. If you are editing an existing rehab corridor, any modifications you make to the Rehab Parameters will update the rehab corridor and the the cross section, profile, and plan views, once you click Apply.
Lane Input
- Number of Left Lanes
-
Specifies the number of lanes on the left side of the road.
- Number of Right Lanes
-
Specifies the number of lanes on the right side of the road.

Lane Parameters
Refer to the appropriate
Rehab and Cross Slope Optimization Subassembly Reference for more information about Lane Parameter properties.
- Ideal Cross Slope
- The desired cross slope (%) for the finished ground profile.
- Overlay Slope Options
- Specifies user defined overlay slope options. Specifies right and left overlay slope options
Tip: Flapping is a term used to describe how the Corrected Cross Slope for an overlay in a rehab subassembly is calculated. Flapping outcomes are different, relative to the Slope Tolerance and the Slope Difference between existing ground cross slope and ideal cross slope. If the Slope Difference is less than the Slope Tolerance for the subassembly, then the use case is considered 'within tolerance'. If the Slope Difference is greater than the Slope Tolerance for the subassembly, then the use case is considered "without tolerance."
Note: Slope Tolerance is an absolute value. Therefore, for either a Slope Difference of 0.4% or -0.4%, both have an absolute value of 0.4%. If the Slope Tolerance is 0.5%, the 0.4% absolute Slope Difference would be considered within tolerance.
- Inside Edge of Lane Offset
- The offset of the start point from the attachment point for calculating existing ground slope.
- Inside Edge of Lane Offset Target
- The offset of the start point from the attachment point for calculating existing ground slope.
- Lane Width
- The distance between the inside edge of lane and the outside edge of lane.
- Lane Width Target
- The object defining the distance between the inside edge of lane and the outside edge of lane. The following object types can be used as targets for specifying this offset: alignments, polylines, feature line, or survey figures.
- Design Lane Width same as Existing Lane
-
- Yes
Specifies that the design lane width is the same as existing lane width
- No
Specifies that the design lane width
is not the same as existing lane width
Note: If No is selected, the Inside Edge of Existing Lane and Outside Edge of Existing Lane parameters will not be applied to the subassembly
- Inside Edge of Existing Lane Offset
- The offset of the inside edge of existing lane from the attachment point.
- Inside Edge of Existing Lane Offset Target
- The object defining the inside edge of lane sample point offset. This will be used to calculate the existing surface slope. The following object types can be used as targets for specifying this offset: alignments, polylines, feature line, or survey figures.
- Outside Edge of Existing Lane Offset
- The offset of the outside edge of existing lane from the attachment point.
- Outside Edge of Existing Lane Offset Target
- The object defining the outside edge of lane sample point offset. This will be used to calculate the existing surface slope. The following object types can be used as targets for specifying this offset: alignments, polylines, feature line, or survey figures.
Rehab Input
- Cross Slope Correction
-
All Lanes Use Same Ideal Cross Slope
-
- Ideal Cross Slope
-
The desired cross slope (%) for the finished ground profile.
- Slope Tolerance
-
Specifies the maximum change to the existing ground profile cross slope (%) that you want to design for.
- Use Superelevation
-
If you Use Superelevation, Ideal Cross Slope will be defined by the superelevation value for the station, as defined by the superelevation table for the alignment.
Vertical Adjustment
- Mill and Level Type
- The type of milling and leveling layer.
- Overlay Depth
- The depth of the overlay layer.
- Minimum Level Depth
- The minimum depth of the leveling layer.
- Minimum Mill Depth
- The minimum depth of the milling layer.
- Apply
- Applies your Rehab Parameters to the selected rehab corridor region and updates the cross section view for the selected station.
