About Rehab Corridor Sections

Use the Rehab Corridor Editor to view and modify rehab corridor sections and to visually inspect how rehab subassemblies are applied at various chainages within rehab corridor regions.

When you select a rehab region within a rehab corridor, three default viewports will be displayed, allowing you to view the corridor cross section for the chainage (cross section view), the vertical profile for the section (profile view) and the location of the corridor cross section along the rehab corridor's alignment (plan view).

Note: The cross section view for the chainage is displayed in the cross section viewport. Critical points such as lane width, accepted crossfall, offset, milling and/or levelling depth and any associated design geometry violations are identified. For the plan and profile views, the chainage tracker identifies the selected chainage within the rehab corridor region. The selected chainage is also displayed in the Rehab Corridor Editor ribbon tab. For example, in the image above, all three viewports are displaying views for chainage 1+80.00'.

Cross Section View

The cross section view shows important information such as width, slope, offset, mill and/or level depth and any potential violations.
Note: You can use Code Set Style in View/Edit Corridor Section Options to customise the information displayed in the cross section view.
  • Width: The width of the lane at the selected chainage.
  • Slope: The accepted crossfall (%) for the selected chainage.
  • Offset: The distance of the outside edge of the lane from the road centreline.
  • Mill/Level Depth: The depth of the milling and/or levelling layer at the selected chainage.
  • Violations: Hover your cursor over a violation icon to view violations.
    Note: There are four possible violation types:
    • Slope

      If the absolute value of Slope Difference is greater than the absolute value of Slope Tolerance, a violation is displayed.

      If Corrected Crossfall is not equal to Ideal Crossfall, a violation is displayed.

    • Relative Gradient

      If the change in corrected slope between two chainages relative to the distance in length between the chainages is greater than the maximum relative gradient, a violation is displayed.

    • Lane Break

      If the difference in accepted slope between two lanes is greater than the maximum lane break slope, a violation is displayed.

Plan View
Profile View
  • Existing Ground (EG)

    Level of the existing ground profile for the selected chainage.

  • Design Profile

    Level of the design profile for the selected chainage. The design profile level for a rehab corridor region is defined by the vertical baseline that was assigned to the rehab corridor in Corridor Properties during rehab corridor creation.

  • Adjusted Level:

    For an undivided rehab corridor section, Adjusted Level is equal to the crown point level for the selected chainage.

    For a divided rehab corridor section, the Adjusted Level is equal to the level of the highest level crown point of any other crowned subassembly in the assembly. If no crown point exists in the assembly, Adjusted Level is set to equal to the Design Profile level. If the assembly has a central reservation on the centreline that separates the right and left lanes, the adjusted level is equal to the design profile level. If there is not a subassembly attached to the baseline, the adjusted level is equal to the design profile level.
