All roadways open to traffic (including, but not limited to, newly paved surfaces, cold milled surfaces, asphalt surface treatments, flush seals, fog seals, and tack coats) will have temporary dashed centerline markings, no passing zone markings, and applicable lane lines placed prior to nightfall. For prime coats, the existing signing will remain in place until the prime coat has cured for 72 hours and temporary pavement marking is installed. Following the 72 hour cure period for prime coats, the Contractor will install temporary dashed centerline markings, no passing zone markings, and applicable lane lines prior to nightfall. Interstate highways will also be marked with edge lines prior to nightfall.
Unless otherwise shown on the plans, centerline and the applicable lane lines may be temporarily marked by temporary pavement marking tape, temporary raised pavement markers, temporary flexible vertical markers (tabs), or temporary pavement marking paint. The material used to mark the no passing zones will be the same type of material used to mark the temporary dashed centerline, unless otherwise approved by the Engineer. For 2 lane roadways with average daily traffic volumes of 2500 or less, no passing zones may be identified using DO NOT PASS and PASS WITH CARE signs rather than pavement markings. The DO NOT PASS signs will be used to mark the beginning of each no passing zone, and the PASS WITH CARE signs to mark the end of each zone. These may be utilized in place of the pavement markings normally used to identify no passing zones for no longer than 14 calendar days. The placement of the dashed centerline marking, and these signs will be required prior to nightfall. The Contractor will take the steps necessary to ensure the temporary markings on the final surface will match the markings on the existing surface. The Engineer will determine locations and limits of no passing zones in accordance with Part 3 of the MUTCD. 2.Materials for Temporary Pavement Marking: Temporary pavement marking tape, temporary raised pavement markers, temporary flexible vertical markers (tabs), and temporary pavement marking paint will be of the type specified and will meet the following requirements. a.Temporary Pavement Marking Tape: Temporary pavement marking tape will be applied according to the manufacturer's recommendations.

If temporary raised pavement markers are used to substitute for dashed centerlines, the dashed centerline will be a 4 foot long line with a cycle length of 40 feet. A 2 foot long line with a cycle length of 20 feet will be used for roadways with severe curvature. Two temporary raised pavement markers will represent the dashed centerline, one at each end of the line. A solid line will be represented by a 5 foot spacing. c.Temporary Flexible Vertical Markers (Tabs): Temporary flexible vertical markers (tabs) will be applied according to the manufacturer's recommendations. 4 inch wide reflectorized markers may be used in place of tape or paint. If temporary flexible vertical markers (tabs) are used to substitute for dashed centerlines, the dashed centerline will be a 4 foot long line with a cycle length of 40 feet. A 2 foot long line with a cycle length of 20 feet will be used for roadways with severe curvature. Two temporary flexible vertical markers will represent the dashed centerline, one at each end of the line. A solid line will be represented by a 5 foot spacing. When an asphalt surface treatment, fog seal, or flush seal are to be applied, temporary flexible vertical markers (tabs) will not be placed more than 72 hours prior to covering the in place markings on the surface. The protective marker covers will not be removed until after all oil within 2 feet of the markers has been applied and rolling has been completed. d.Temporary Pavement Marking Paint: Temporary pavement marking paint will be applied in accordance with Section 633 except as modified by the following: Dashed centerlines will be applied in 4 inch widths 4 feet long at cycle lengths of 40 feet. A 2 foot long line at cycle lengths of 20 feet may be used for roadways with severe curvature. Solid lines will be 4 inches wide for the length specified or required. The paint applicator will be a self-propelled pneumatic spraying machine with atomizing nozzles capable of applying a minimum of two lines at one time from 4 to 8 inches wide. When only one lane of a two-lane roadway is complete at the end of a day, the temporary marking will be placed near centerline on the unsurfaced portion of the roadway. M.Removal of Pavement Markings: Pavement markings to be removed will be designated by the Engineer. Pavement markings will be removed from the pavement by methods that do not damage the surface or texture of the pavement. Pavement markings will be removed before the traffic pattern is changed. Covering the markings is not acceptable removal. 634 Page 447Sand or other material used for removal will be disposed of as the work progresses. Accumulations of sand or other material, which interferes with drainage or constitutes a hazard to traffic, will not be permitted. When sand blasting is used for removal of pavement markings or objectionable material, and the removal operation is performed within 10 feet of a lane occupied by the traveling public, the residue including dust, will be removed immediately by a vacuum attachment operating concurrently with the sand blasting operation. Damage to the pavement surface caused by pavement marking removal will be repaired at the expense of the Contractor.
