620.03 Construction Requirements
620.03.1 General
Furnish a manufacturer’s material certification or data sheet for the product to be used. Do not apply materials that do not meet the contract requirements. The Project Manager may request a manufacturer’s sample or take field samples for testing. Furnish a material sample weighing at least 2 pounds (0.91 kg). Furnish temporary waterborne traffic paint, waterborne traffic paint, epoxy traffic paint, and glass beads listed on the QPL .
620.03.2 Layout of Pavement Markings
The Project Manager will lay out the final pavement marking configurations and locations. Notify the Project Manager a minimum of 10 business days before striping in the permanent location is to begin. Preserve all marking configurations and locations after the initial layout by the Department. Apply the markings to within ± ¼-inch (6 mm) of the specified width. Apply the centerline and shoulder lines within 0.30 feet (90 mm) of the true line. Ensure the stripe does not deviate by more than 0.15-foot in 500 feet (45 mm in 150 m). Apply all other markings (words, symbols, stop bars, crosswalks, hash marks, and others) within 0.25 feet (75 mm) of the location marked by the Project Manager. Apply words, symbols, letters, and/or numeral pavement markings free of gaps and fully solid. The Project Manager will determine the accuracy of the applied markings. Remove and replace out of specification pavement markings as directed at Contractor expense.
620.03.3 Equipment
Use equipment manufactured to apply the material type. Ensure the equipment prevents paint spray or bead loss outside the specified line width. Equip the pavement-marking machine with a flow meter and totalizer that measures paint quantities in gallons (L), to the nearest 0.1 gallon (0.1 L). Calibrate the flow meter before use on the project and when directed. Locate the flow meter in the flow line to the spray nozzles. Locate the totalizer where it can be easily read. Ensure the calibration adjustment is accessible without meter removal or using a calibration adjustment device. 620 – PAVEMENT MARKING APPLICATION 2020 EDITION V5.1 620-2 Ensure the application equipment is acceptable to the manufacturer. Submit calibration certificates from an independent agent for the paint tank. Re-certify the tank at the beginning of each year before using the equipment on Department contracts. The Project Manager may inspect the tank before each use and as determined necessary. Stop bars, crosswalks, and words/symbols may be applied with hand-operated equipment. Terminate marking application when the equipment fails to apply the markings in accordance with the contract requirements. Make equipment adjustments and resume striping. For material paid by the gallon (L), quantities will be verified by measuring the equipment’s paint tank(s), using tank stabs. The Project Manager will visually witness tank stabs at the beginning and end of each work shift, any time additional paint is added to the tank, at the beginning and end of each route/road segment on contracts with multiple route/road segments, at the beginning and end of each certified paint lot, and at other intervals as necessary. Park the equipment on a level surface approved by the Project Manager for each tank measurement.
620.03.4 Surface Preparation and Weather Limitations
A.General. Prepare the surface to be painted in accordance with the paint manufacturer’s recommendations. Remove loose material by sweeping and brooming no more than 2 days before striping. If not bid separately, the cost of this operation is included with the cost of the striping and is not measured separately for payment. Inform the Project Manager and modify, when required, the surface preparation to ensure optimal bonding of the marking to the surface and to provide the specified marking requirements. Apply the material following the manufacturer’s recommendations. Apply pavement markings during daylight hours only. Obtain Project Manager approval to apply pavement markings any other time. Grind all surfaces with existing epoxy pavement markings within 3 calendar days before applying the pavement markings. Grinding is surface abrasion to provide a roughened surface free of loose paint chips, loose seal aggregate and surface debris. Grind to a depth that completely removes the existing pavement markings. Immediately stop grinding if the depth exceeds that of the existing pavement markings and adjust meet the specified grind depth.
B.Concrete Surfaces. Prepare existing concrete surfaces in accordance with Subsection
620.03 4(A)
. Do not grind or apply final pavement markings on new concrete until 30 calendar days after it has been placed.
C.Removal Limits. Meet the following removal limits: • Do not grind more than 1-inch (25 mm) wider than the existing stripe. • Do not grind more than 4 inches (100 mm) from the beginning or end of the stripe being removed.
D.Disposal. Collect and dispose of all removed material and new traffic marking materials spilled during the work. Process, handle, transport, and dispose of the materials in accordance with the current applicable solid waste laws and regulations.
620.03.5 Temporary Striping
Temporary striping consists of the centerline markings for two-lane two-way roadways; lane line markings for divided four-lane Interstates, and centerlines and lane lines for two-way undivided three or more lane roadways. Divided roadways are roadways where the paved surface for each direction of travel is physically separated by an unpaved section. 2020 EDITION V5.1 PAVEMENT MARKING APPLICATION – 620 620-3 Apply temporary striping for paving and milling operations in accordance with Subsection
618.03 9.
Remove, at Contractor expense, all temporary striping that conflicts with interim or final pavement markings. Remove conflicting temporary stripe(s) the same day the interim or final pavement markings are applied.
A.Temporary Waterborne Traffic Paint. Apply a 10 ± 1 mil (0.254 ± 0.025 mm) thick wet film immediately followed by applying at least 6.0 pounds per gallon (0.72 kg/L) of glass beads to temporary striping.
B.Tape. Follow the tape manufacturer’s recommendations for road surface preparation and installation. Install the tape in accordance with the contract.
C.Raised Pavement Markers. Follow the raised pavement markers manufacturer’s recommendations for road surface preparation and installation. When substituted for line markings, install raised pavement markers in accordance with the following:

2.3 markers evenly spaced for each skip line.
620.03.6 Interim Pavement Markings
Interim pavement markings consist of all longitudinal striping (centerlines, edge lines, lane lines, etc.) and words and symbols identical to the final pavement marking configuration. Use the material specified in the contract. Apply interim pavement markings no later than 14 calendar days after the application of temporary striping. Do not apply interim pavement markings when the ambient air temperature is lower than 40 °F (4 °C). Apply the interim pavement markings matching the final pavement marking configurations and locations. Interim pavement markings placed prior to chip seal may be offset as approved by the Project Manager. The Project Manager will suspend all remaining contract work if the interim striping is not applied within the time specified above.
A.Waterborne Traffic Paint. Apply a 16 ± 1 mil (0.406 ± 0.025 mm) thick wet film immediately followed by applying at least 8.0 pounds per gallon (0.96 kg/L) of Montana Type 2 glass beads.
620.03.7 Final Pavement Markings
Apply final pavement markings a minimum of 30 calendar days, and a maximum of 45 calendar days for the following: • After concrete is placed. • After microsurfacing operations. • New asphalt pavement that will not receive a surface treatment. • After seal coat operations through initial sweeping are completed. Fog sealed surfaces must be free of excess asphalt emulsions and oils. When final pavement markings are the only remaining item of work on the project, contract time assessment will be suspended for 45 calendar days or until beginning final pavement marking applications, whichever is less. The Project Manager may extend the 45 days due to holidays or inclement weather that prevents the application of final pavement markings. Use the material specified in the contract. 620 – PAVEMENT MARKING APPLICATION 2020 EDITION V5.1 620-4

Remove all pavement markings that would conflict with newly applied striping or markings at contractor expense. Remove conflicting pavement markings the same day new markings are applied. Remove sand or other material on the surface left by the removal as the work progresses. Satisfactorily repair surfaces damaged by marking removal at Contractor expense.
620.04 Method of Measurement
620.04.1 Temporary Striping Quantities
Temporary striping is measured by the linear foot (m) to the nearest foot (0.1 m) of actual 4- inch (100 mm) stripe applied. Lines wider and narrower than 4 inches (100 mm) are converted to the equivalent linear feet (m) of 4-inch (100 mm) wide line. Only those pavement markings represented by a manufacturer’s certification at the time of application and used and witnessed on the project are eligible for payment.
620.04.2 Interim Pavement Marking Quantities
Interim pavement markings are measured by the gallon (L). Only those pavement markings represented by a manufacturer’s certification at the time of application and used and witnessed on the project are eligible for payment. Should the actual quantity measured by the Project Manager using tank stabs or totalizer exceed the quantity calculated using an application rate of 17 mils (0.431 mm) times the specified width (without applying the tolerance) times the length of line applied, the lesser quantity will be paid for.
620.04.3 Epoxy Traffic Paint
Epoxy is measured by the gallon (L). Only those pavement markings represented by a Manufacturer’s Material Certification at the time of application and used and witnessed on the project are eligible for payment. Should the actual quantity measured by the Project Manager using tank stabs or totalizer exceed the quantity calculated using an application rate of 22 mils (0.559 mm) times the specified width (without applying the tolerance) times the length of line applied, the lesser quantity will be paid for.
620.04.4 Preformed Plastic Materials
Preformed plastic and thermoplastic pavement striping is measured by the foot (m). Words and symbols are measured by the square foot (m 2). 620 – PAVEMENT MARKING APPLICATION 2020 EDITION V5.1 620-6
620.04.5 Curb Painting
Painting curb is measured by the gallon (L).
620.04.6 Hand Painted Pavement Markings (Words and Symbols)
Hand painted pavement striping, words and symbols; stop bars, crosswalks, hash marks, and other striping not applied by a striping truck are measured by the gallon (L). Quantity measurements are based on flow meter/totalizer readings taken before and after each run or if a calibrated tank is used, tank measurements are taken before and after each run. Computerized quantity print outs will be compared against tank stabs and the quantity calculated based on the surface area times the application rate for the product used. The amount of paint measured for payment is the difference between the startup readings and the end readings. Should the actual quantity measured by the Project Manager using tank stabs or totalizer exceed the quantity calculated using the application rate times the surface area applied, the lesser quantity will be paid for. All readings that measure paint for payment will be taken by the Project Manager. Provide all necessary assistance to make the readings including sufficient notice before the paint work begins.
620.04.7 Removal of Pavement Markings
If bid separately, pavement striping removal is measured by the foot (m) based on a 4-inch (100 mm) width for the actual quantity of striping removed. Lines wider and narrower than 4 inches (100 mm) are converted to the equivalent linear feet (m) of 4-inch (100 mm) wide line. Removal of words and symbols is measured by the square foot (m
2.and converted to the equivalent linear feet (m) of 4-inch (100 mm) wide line. If not bid separately, removal of pavement markings is incidental to other items and is not measured separately for payment.
620.04.8 Line Control
Establishing line control for pavement markings is not measured for payment.
620.05 Basis of Payment
Payment for the completed and accepted quantities is made under the following: Pay Item Pay Unit Curb Painting Gallon (L) Plastic Markings Square Foot (m2) or Linear Foot (m) Remove Pavement Markings Square Foot (m2) or Linear Foot (m) Striping Gallon (L) Temporary Striping Linear Foot (m) Words & Symbols Gallon (L) Line control is not paid for separately but is included in the cost of the pavement markings. Interim stripe applied over temporary stripe is measured and paid for as interim stripe. The quantity that is paid for marking materials is the lesser of the following quantities: • Flow meter and totalizer. • Calibrated tank and measuring device (tank stabs); and • Surface area times the application rate specified.
