The placement and removal of temporary or permanent pavement markings in work zones is a challenging process. This placement and removal process of temporary pavement marking within the work zone may at times create “ghost markings” that conflict with permanent markings that are placed at project completion. Moreover, temporary markings may fail to remain in place. The process and timing associated with placing or removing pavement markings may interrupt or impede paving operations and require extensive contractor coordination. Because of these issues, it is common practice for pavement marking placement and removal to be a significantly delayed sub-phase of construction, thereby increasing the risk of incidents or crashes within the work zone.
This objective of this synthesis is to document state department of transportation (DOT) practice for pavement marking placement and removal in work zones. The study will address practices for marking placement and removal, marking materials used, and safety considerations. In addition, the synthesis will identify examples of DOT strategies for solving or alleviating specific problems associated with pavement marking in work zones.
Information will be gathered through literature review, a survey of DOTs, and interviews with selected agencies for the development of case examples. Knowledge gaps and suggestions for research to address those gaps will be identified.
