ShoulderVariesExtensions

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 which side to place the subassembly.	Left/Right	Right
Insertion Point	Specifies insertion point of the lane either at the crown, or at the edge of travel way.	Crown/ EdgeOfTravelWay	Crown
Crown Point on Inside	Specifies that inside edge of travelway be coded as Crown.	Yes/No	No
Width	Width of the lane from the offset of the inside edge to the offset of the outside edge.	Numeric, positive	12 ft 3.5 m
Base Depth	Depth of base course.	Numeric, positive	0.33 ft 0.1 m
Default Slope	Default slope of the lane to be used when the superelevation slope for the alignment is not defined.	Numeric	-2.00 ( % )
Pave1 Depth	Thickness of the Pave1 layer (zero to omit).	Numeric, non-negative	0.083 ft 0.025 m
Pave2 Depth	Thickness of the Pave2 layer (zero to omit).	Numeric, non-negative	0.083 ft 0.025 m
Subbase Depth	Thickness of the subbase layer (zero to omit).	Numeric, non-negative	1 ft 0.3 m
Pave2 Extension	Extension Beyond Pave1.	Numeric, non-negative	0.5 ft 0.15 m
Base Extension Slope	% slope of the base extension.	Numeric	-2.00 ( % )
Base Extension	Extension Beyond Pave2.	Numeric, non-negative	0.5 ft 0.15 m

Target Parameters

This section lists the parameters in this subassembly that can be mapped to one or more target objects. For more information, see To Specify Corridor Targets.

Parameter	Description	Status
Target Outside Elevation	May be used to override the shoulder slope and the outside shoulder edge to the elevation of a profile. The following object types can be used as targets for specifying this elevation: profiles, 3D polylines, feature lines, or survey figures.	Optional
Target Width	May be used to override the shoulder width and tie the shoulder width to an offset alignment. The following object types can be used as targets for specifying the offset: alignments, polylines, feature lines, or survey figures.	Optional

Runtime Logical Assignments

None.

Lane Slope	% slope of the lane	Numeric

Behavior

The finish grade of the shoulder is inserted for the given Shoulder Width and Default Shoulder Slope outward from the attachment point. The Pave2 points and links are then drawn. A Pave2 extension is provided using the input parameters. The Base points and links, including extension, are calculated using the input parameters. The Subbase points, links, and shape, including extension, are calculated using the input parameters.

Layout Mode Operation

In layout mode the subassembly displays the links comprising the shoulder.
