PermeablePavement

Attachment

The attachment point is at the inside edge of the permeable pavement. This component can be attached to either the left or right side.

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.

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
Underdrain Invert	May be used to override the invert underdrain elevation. The following object types can be used as targets for specifying the elevation: profiles, 3D polylines, feature lines, or survey figures.	Optional
Pavement Elevation	May be used to override the pavement slope. The following object types can be used as targets for specifying the elevation: profiles, 3D polylines, feature lines, or survey figures.	Optional
Permeable Pavement Width	May be used to override the pavement width. The following object types can be used as targets for specifying the width: alignments, polylines, feature lines, or survey figures.	Optional
Underdrain Target	May be used to override the pipe offset value and tie the pipe to an offset alignment. The following object types can be used as targets for specifying the width: alignments, polylines, feature lines, or survey figures.	Optional

Runtime Logical Assignments

None.

Output Parameters

None.

Behavior

The slope of the permeable pavement is determined by the input parameters or, if set, the offset targets. The shape of the permeable pavement is built from the input parameters. If set to use an underdrain, an underdrain pipe and surrounding material is constructed. The location of the underdrain is at the edge of the pavement, unless the targets change the location and elevation. If set to include an impermeable liner, link codes are assigned to the bottom and outer sides of constructed links.

Layout Mode Operation

In layout mode, this subassembly draws the permeable pavement to the input parameters.
