Pavement Marking Plan Sheets depict the final pavement marking layout on a base map to show the relationship between the pavement markings and the other roadway elements.
The Pavement Marking Plan Sheets typically show the entire extents of the proposed roadway plans work plus any additional areas outside the roadway limits where pavement marking modifications are required. Existing pavement marking in the proposed roadway construction limits shall not be shown. Extend the basemap and show the existing pavement markings of all highway tie ins a minimum of 200' beyond the roadway construction limits. (Elaborate or determine if 200' beyond is necessary)
The standard scale for Pavement Marking Plan Sheets is the same scale as the Roadway Plan Sheets, typically 1" = 50'. For NCDOT projects, full size sheets shall be 34" W x 22" H and half size sheets shall be 17" W x 11" H.
The scale for Pavement Marking Plan Sheets may vary based on the detail required. If a sheet is overly crowded such that the sheet becomes illegible, a different scale may be required (discuss with Project Engineer). Care should be given to provide a consistent scale on a project or a specific corridor on the project.
Mainline roadway should be continuous through the sheet sequence and horizontal to the bottom of the plan sheet. Scale will be 1" = 50' for full size and approximately 1250' mainline coverage per sheet. Interchanges should be laid out such that the full details of the mainline and cross street are shown, which may require two separate plan sheets (or inset within plan sheet). Each sheet should begin and end on even 100' stations where possible. Match lines are required to provide reference to the adjoining sheet. Break lines may be used between pages or on the same page when there is no change in the number of lanes, there is no change in the pavement marking line type(s) or there are no bridges to be shown.
Stations shall increase from left to right on the sheet. The order and orientation of the sheets shall follow the order and orientation of the roadway sheets to the extent possible. In general, match lined -Y- lines shall appear in numerical order if following the roadway order. If additional sheet coverage is necessary, the additional sheets shall appear in a logical order and may break the numerical order of the -Y- lines.
Base mapping is used to convey the existing or proposed roadway network on the Pavement Marking Plan Sheets. The type of base mapping shall be agreed upon during the scoping process and should include the source of the base mapping and the level of detail needed.
Sources for the base mapping may include the following in order of preference:
• Roadway CAD (proposed roadway plans/adjacent project pavement marking plans) – If available, this is the primary source of base mapping.
• Existing survey data – shall be used on all areas outside of the proposed roadway where available
• Aerial photography – edge of travel and pavement markings traced from the latest available aerial photography
Physical features within or adjacent to the travel way relating to pavement marking design should be shown in the pavement marking base map. This includes, but is not limited to:
- Pavement Marking Design
- Edge of Pavement
- Curb & gutter
- Paved shoulders (shaded light gray– optional)
- Bridges (shaded light gray)
- Walls (noise and retaining walls)
- Sidewalks (shaded light gray)
- Curb ramps
- Raised monolithic islands (shaded light gray)
