Testimonials: Chip Seal Markers
PENNSYLVANIA DOT
Pennsylvania DOT: The department's regulation on work zone traffic control requires all center lines and lane lines that were covered or destroyed as a result of the work operation to be replaced with standard or interim pavement marking patterns prior to terminating work each day... In an effort to provide a safer environment and better guidance for drivers on oil and chip projects, Engineering District 1-0 has again experimented with the Davidson flexible chip seal and slurry seal TRPM.
It is our opinion that if, in good engineering judgment, it is determined that oil and chipping operations fall into the category of providing a surface texture that will not accept temporary pavement marking tape as interim markings, and it would be safer to use the approved raised pavement markers, you should do so.
Washington State DOT: A new type of raised reflective temporary lane marker is being made by Davidson. It has its own adhesive, is very simple to install, and comes in either white or yellow... These new markers can be installed two or three times as fast as other kinds, and workers do not have to bend over nearly as long out in the middle of the roadway. That's a very big plus on the safety side of things for work areas which are still under traffic.
Alberta Transportation: It is strongly recommended that Alberta Transportation use these temporary lane markers on all seal coating projects. They provide the quickest and most efficient method of re-establishing temporary lane markings. This means a considerable increase in safety to the traveling public. The fact that the markers provide instantaneous lane lines is their greatest asset. Since safety is paramount in seal coating operations, these markers are invaluable.
U.S. Department of Transportation, Federal Highway Administration: These types of markers are appropriate to be used either as a supplement to pavement markings or as a substitute for pavement markings. When these types of markers are used, they must be spaced in accordance with Sections 3B-14, 3B-15, and 3B-16 of the MUTCD. These sections of the MUTCD provide specific spacing requirements that must be followed. We find that your type of raised pavement marker is effective in certain situations such as providing delineation on chip seal paving projects.
