2580Interim Pavement Marking

2580.1DESCRIPTION

This Work consists of placing interim pavement markings on those pavements, prior to opening them to traffic, where the in-place surface is to be covered by a subsequent paving course or the permanent lane markings are to be placed at a future date.

2580.3CONSTRUCTION REQUIREMENTS

A Application When centerline or lane markings (excluding edgelines) are removed, apply the interim pavement markings prior to opening the Roadway to traffic. Apply edgelines within 14 Calendar Days of opening Roadway to traffic. Apply the interim pavement marking on a clean, dry pavement surface, free of dirt and foreign matter as recommended by the Material manufacturer and as required by Contract. Follow the manufacturer’s specifications for installation procedures and Materials. When final markings are to be multi-component liquid and paint is used for interim solid lines, a 10 mil thick Layer application of a water-based traffic marking paint shall be used. With a 10 mil Layer of paint applied, beads should be applied at a rate of 6 pounds per gallon. Removal of the 10 mil L ayer of paint is not required prior to placing the multi-component liquid. If the Layer of paint is greater than 10 mils, removal is necessary prior to placing the multi-component liquid. Interim markings shall consist of centerline markings including no passing zone markings, painted islands, and lane lines (excluding edgelines, crosshatching, and pavement messages) in accordance with the Minnesota Manual on Uniform Traffic Control Devices (MN MUTCD). Provide interim markings with a width equal to the corresponding permanent pavement marking and with a cycle length as indicated in the Plan. Lateral placement of the markings from centerline shall be as directed by the Engineer. B Tolerance Conform with the following interim striping tolerances: A tolerance of plus 1/4 inch and minus 0 inch from the specified width will be allowed for striping provided the variation is gradual and does not detract from the general appearance . Lengths for the broken line segments may vary no more than ±3 inches. Place longitudinal markings 2 inches ± 1 inch

from the edge of pavement or longitudinal (centerline) joint. Also, pertaining to the cycle length, the total allowance for the line segment and gap shall be no more than ± 3 inches. Establishment of application tolerances shall not relieve the Contractor of their responsibility to comply as closely as practicable with the planned dimensions. Interim markings on the final pavement surface shall match the location of the final markings. In the event the Engineer determines the interim striping is out of tolerance, take corrective action. Remove pavement markings utilizing Equipment that is not detrimental to the final surface, as required by the Engineer. Costs associated with removing and restriping the interim markings will be at the Contractor’s expense. This would include any costs associated with repairing damage caused to the wearing course after pavement marking removal. C Temporary Raised Pavement Markers When Temporary Raised Pavement Markers (TRPM) are used as interim markings, install per the Plan. Removal of TRPMs shall be included in the 2580, “Interim Pavement Marking, “ Pay Item. D Maintenance and Removal Maintain and replace the interim markings without additional compensation until they are covered by the next paving course, are replaced with permanent pavement markings, or final acceptance of the Project is made. Remove TRPMs and pavement marking tape between pavement courses, except for TRPMs used with seal coats. Remove TRPMs used as Interim pavement markings. Remove any solid line delineations on the final pavement surface marked with p avement marking tape prior to placing the permanent pavement markings. The Engineer may require the removal of any Interim pavement markings that will interfere with the placement of the permanent markings or could cause confusion to the traveling public if left in place. Removal of Interim pavement markings, if required, shall be included in the Pay Item, and shall be in accordance with 2102, “Pavement Marking Removal.” Waste from installation, removed marking Material and removal media shall become property of the Contractor. Dispose of all waste generated by Interim pavement marking removal process in accordance with 1701, “Laws to be Observed,” and 1717, “Air, Land, and Water Pollution.”

2580.4METHOD OF MEASUREMENT

A Length Interim pavement markings will be measured by the actual length in linear feet of each line marked as indicated in the Plan and will not include the gap between line segments . No additional quantity will be included for repair or renewal Work. Measurement for TRPMs will be made according to the length of line being simulated. B Lump Sum The Engineer will not measure Interim pavement markings placed, maintained, and removed if the Contract specifies Interim pavement markings as a lump sum.

2580.5BASIS OF PAYMENT

Payment for Interim pavement marking at the Contract price per unit of measure shall be compensation in full for costs of furnishing and placing the marking, removal if required, and necessary maintenance and renewal Work. A Monetary Adjustments The Department must apply Incentives and Disincentives and may apply monetary deductions for Interim pavement marking. The amounts of these adjustments are deemed reasonable. If the Contractor is negligent in adhering to the provisions set forth in 2580.3B , “Tolerance,” the Department will assess an hourly charge at a rate of $250.00 per hour for each hour or any portion thereof which the Engineer determines that the Contractor has not complied.
