ShoulderVerticalSubbase

Attachment

The attachment point is at the inside edge of the paved shoulder, which is typically at the outside edge-of-traveled way.

Input Parameters

Note: All dimensions are in meters or feet unless otherwise noted. All slopes are in run-over-rise form (for example, 4 : 1) unless indicated as a percent slope with a “%” sign.

Parameter	Description	Type	Default
Side	Specifies to insert the subassembly either on the right or the left side of the attachment point.	Left/Right	Right
Paved Width	Width from the attachment point to the edge of paved shoulder	Numeric	2.4 m 8.0 ft
Use Superelevation Slope	Specifies to use superelevation slope, from the superelevation specification defined on the baseline alignment, for the paved portion of the shoulder.	Selection List: No Left Outside Shoulder Left Inside Shoulder Right Inside Shoulder Right Outside Shoulder	No
Shoulder Slope Direction	Specifies whether the shoulder slopes away from the crown or towards the crown	Selection List: Away from Crown Towards Crown	Away from Crown
Default Paved Slope	Default slope of the paved shoulder, if a superelevation slope is not specified.	Numeric, Grade	-6.000%
Unpaved Link Treatment	Determines when or if the unpaved portion of the shoulder is inserted. Value should be one of the following: Code: Treatment 1: Always used 2: Used only if shoulder is in cut 3: Used only if shoulder is in cut, or is in fill on the high side of superelevation.	Numeric, 1 – 3	1
Unpaved Width	Width of the unpaved portion of the shoulder. Set to zero to omit the unpaved link.	Numeric, positive	1.8 m 6.0 ft

Target Parameters

This section lists the parameters in this subassembly that can be mapped to one or more target objects, such as a surface, alignment, or profile object in a drawing. For more information, see To Specify Corridor Targets.

Parameter	Type of Assignment	Status
Paved Width	May be used to override the fixed Paved Width and tie the edge-of-shoulder to an offset alignment. The following object types can be used as targets for specifying this offset: alignments, polylines, features lines, or survey figures.	Optional
Daylight Surface	Used to determine if the outside edge of paved shoulder is in cut or fill. This parameter is not needed if the Unpaved Link Treatment is 1. The following object types can be used as targets for specifying this surfaces: surfaces.	Conditional; required if Unpaved Link Treatment is 2 or 3.

Output Parameters

Shoulder Width	Width of the paved shoulder	Numeric
Shoulder Slope	Slope of the paved shoulder	Numeric

Behavior

The links for the shoulder finish grade, Pave1, Pave2, Base and Subbase are inserted outward using the given Paved Width, Paved % Slope, material depths. If the Unpaved Link Treatment is 1, the unpaved shoulder link is inserted under all conditions. If the Treatment code is 2, the outside edge of the paved shoulder is checked to determine if it is in cut or fill; the unpaved shoulder link is inserted only in cut. Treatment code 3 uses the unpaved link in cut, or when the paved shoulder link has a positive %slope.The unpaved finish grade link is inserted at the given Unpaved % Slope, unless the difference between the Paved %Slope and Unpaved %Slope exceeds the Unpaved Max Breakover value. In that case the slope of the unpaved link is adjusted to hold the difference to the given breakover..

Layout Mode Operation

In layout mode, this subassembly displays the links comprising the shoulder for the normal crown roadway condition, based on the input parameters provided. If a numeric value is given for the Paved %Slope, the paved portion of the shoulder is calculated based on that value. Otherwise the default value of -6% is used.
