This subassembly inserts a paved shoulder with all layers including subbase extended to a daylight point. Optionally you can reduce the depths of various sublayers to interlace subbase material around some of the select material layers.
The attachment point is at the inside edge of the paved shoulder, which is typically at the outside edge-of-traveled way.
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.
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 in the AutoCAD Civil 3D User’s Guide Help.
| Parameter | Description | Status |
|---|---|---|
| Shoulder Width | Can be used to override the fixed Shoulder 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 |
| Parameter | Description | Type |
|---|---|---|
| Daylight Slope | Slope of the daylight link | Numeric |
| Daylight Offset | Offset of the subgrade daylight point | Numeric |
| Daylight Elevation | Elevation of the subgrade daylight point | Numeric |
| Shoulder Width | Width of the paved shoulder | Numeric |
| Shoulder Slope | Slope of the paved shoulder | Numeric |
The finish grade of the shoulder is inserted for the given Shoulder Width and Default Shoulder Slope outward from the attachment point. The subbase link is inserted from the attachment point starting at the Subbase Depth below the finish grade.
The shoulder daylight link can be inserted with either a fixed slope (Hold Daylight Slope = True), or a fixed width (Hold Daylight Slope = False). If a fixed slope is used, the daylight link is extended from the outside edge of the shoulder until it intersects the subbase link. Otherwise, the subbase layer is extended for the Daylight Width beyond the outside edge of the shoulder, and the daylight link is connected to the end of the subbase.
If topsoil material is set to “a positive” value then a new material layer is introduced to the specified thickness right below the daylight link. The thickness is measured perpendicular to the shoulder daylight ink. This layer extends from the top layer of the shoulder to the subgrade daylight link at the bottom. Due to this new layer provision, width of the shoulder top layer will be adjusted as shown in the following illustration.
The Pave1, Pave2, and Base surface links are inserted parallel to the finish grade at the given depths until they intersect with the shoulder daylight link.
If the above trim values are set for a positive value then top of respective material will be shortened by that value and the bottom link will be derived with material side slope equal to the daylight slope.
Further, if the “gap between Pave1/Pave2 and/or Pave2/Base” is set to a positive value – then those lavers will be separated by that gap as shown in the illustration below.
If the gaps between Pave1/Pave2 and Pave2/Base are set to ZERO then the subassembly will be drawn as shown below.
If the sub-layers are set with zero trim values, then this subassembly will be similar to the ShoulderExtendAll subassembly with optional topsoil lining.
In layout mode this subassembly displays the links comprising the shoulder with default parameters assigned to it.
The following table lists the point, link, and shape codes for this subassembly that have codes assigned to them. Point, link, or shape codes for this subassembly that do not have codes assigned are not included in this table.
