DESCRIPTION
636.01.01 General. This work consists of the application of temporary pavement striping paint and traffic
beads. MATERIALS
636.02.01 General. Material shall conform to the following Sections:
Traffic Paint ................................ ............................................................................................................................................ Section 729 Traffic Beads .......................................................................................................................................................................... Section 730 Use epoxy traffic paint materials for temporary painted striping placed on surfaces to receive permanent epoxy striping. Use waterborne traffic paint materials for temporary painted striping placed on surfaces to receive permanent waterborne striping. Use polyurea traffic paint materials for temporary painted striping placed on surfaces to receive permanent polyurea striping. CONSTRUCTION
636.03.01 General. The finished surface of each course of dense- graded plantmix surface shall be painted
prior to placing public traffic thereon. The pattern for this painting shall closely parallel the pattern shown in the plans for the permanent striping, the requirements of the Special Provisions, or the patt ern shown for traffic control. Properly locate painted traffic lines. Temporary painted pavement markings placed on interstate and full control of access freeways shall be 100 mm (4 in.) wide for edge and lane lines, 200 mm (8 in.) wide for ramp gore lines, and 300 mm (12 in.) wide for stop bars and cross walks. Temporary painted pavement markings used on other roads shall be 100 mm (4 in.) wide, except stop bars and cross walks shall be 300 mm (12 in.) wide. Place railroad markings according to the Standard Plans. The paint pattern for a broken line shall consist of a 3 m (10 ft) stripe and a 9 m (30 ft) gap. Provide paint color and configurations according to the plans and t he MUTCD. If directed to repaint due to normal wear, said work will be measured for payment according to Subsection
636.04.01 Should repainting be required for any purpose other than normal wear as determined by the Engineer,
no additional compensation w ill be allowed for costs. Apply paint to an approved clean and dry surface. Apply by a single application with a machine capable of dispensing beads immediately after paint is applied. Do not use a thinner unless otherwise approved. Apply paint when the ambient air temperature is above 7 ° C (45 ° F). Paint may be applied when the ambient air temperature is below 7 ° C (45 ° F), but above 0 °C (32 ° F), provided the road surface is free of any possible sources of moisture or condensation during application. Use traffic cones or other approved means to protect the pavement striping from public traffic until dry. Do not heat the paint above 63 ° C (145 °F) to reduce drying time. Except for application on open- graded surfaces , apply paint at a rate to produce a m inimum film thickness of 200 μm (8 mils) when dry. Dry film thickness will be determined according to Test Method No. Nev. T510. Apply glass beads at the rate of 720 g/L (6 lb/gal) of paint. Use Type II beads for epoxy or polyurea. 636 TEM PORARY PAINTED PAVEMENT MARKING The application will be checked at the beginning of each day’s striping and as often thereafter as considered necessary. If equipment settings fail to produce quality striping within the limits specified, stop striping until the cause is corrected. Temporary painted striping may be required to be placed on the new plantmix bituminous open- graded surface. See Subsection 632.03.04 for limitations on the application of pavement striping and optional application of temporary painted striping. The location and pattern for temporary striping applied on the new open- graded surface shall closely parallel the location and pattern shown in the plans for the permanent striping. Temporary striping widths shall be as specified above. Apply the temporary painted striping on the new open- graded surfaces to obtain a minimum dry film thickness of 150 μm (6 mils), measured without beads. Apply glass beads at the rate of 720 g/L (6 lb/gal) of paint. Use Type II beads for epoxy or polyurea. There will be no additional compensation for furnishing, applying, and maintaining the temporary painted striping on the new open- graded surfaces before applying the permanent striping. Provide a 30 m geometry reflectometer from one of the manufacturers listed in Subsection 632.03.05 of the QPL for reflectivity requirements. Perform retroreflective measurements according to Test Method No. Nev. T511. The locations and number of measurements will be determined. Maintain all temporary striping throughout the duration of construction in a condition that meets the following requirements: Color Specific Luminance, mcd/(m2۰lux) White ................................ ............................................. 175 Minimum Yellow ................................ ............................................ 125 Minimum If the open- graded surface is not completed and unscheduled winter suspension occurs due to Contractor’s operations, be responsible for all costs for installation and maintenance of temporary striping. The Engineer will determine if the unscheduled winter suspension was due to the Contractor’s operations. Maintain temporary striping during the winter suspension as directed. Comply with dir ectives regarding maintenance of temporary striping within 5 working days. METHOD OF MEASUREMENT
636.04.01 Measurement. Temporary painted striping will be measured by the linear meter (linear foot),
kilometer (mile), or square meter (square foot). Double solid and broken w/solid line s will be considered as a single line when measured for payment. Gaps in broken or dotted lines will be included in the linear measurement. BASIS OF PAYMENT
636.05.01 Payment. The accepted quantities, measured as provided above, will be paid for at the contract
price per unit of measurement for the pay items listed below that are shown in the proposal. Payment will be full compensation for the work prescribed in this Section. Payment will be made under: Pay Item Pay Unit Temporary Painted Striping (*) ................................ .............
