Approved List of White and Yellow Reflectorized Pavement Marking Paints. Project acceptance will be based on the appearance of an approved brand name on the container label. All paints shall conform to Federal, State, and local air pollution regulations, including those for the control (emission) of volatile organic compounds (VOC) as established by the U.S. Environmental Protection Agency, and the New York State Department of Environmental Conservation.

640-3 Construction Details

640-3.01 General. All pavement markings and patterns shall be placed as shown in the contract

documents and in accordance with the MUTCD. Before any pavement marking work is begun a schedule of operations shall be submitted to and approved by the Engineer. When pavement markings are applied under traffic, the Contractor shall provide all the necessary flags, signs, cones, shadow vehicles, flashing arrow boards, etc. to maintain and protect traffic, to protect the work operation, and to protect the painted pavement markings until thoroughly dry and serviceable. No additional payment will be made for these items. The application of pavement markings shall be done in the general direction of traffic. Striping against the direction of normal flow of traffic shall not be allowed.

640-3 02

NEW YORK STATE DEPARTMENT OF TRANSPORTATION Section 600 STANDARD SPECIFICATIONS (USC) January 1, 2026 VOLUME 3 The Contractor shall be responsible for cleaning the pavement, to the satisfaction of the Engineer, of dust, dirt, and other foreign material which may be detrimental to the adhesion of the paint film. When necessary, the Contractor shall establish marking line points at 30 feet intervals throughout the length of the pavement or as directed by the Engineer. The Contractor shall be responsible for removing, to the satisfaction of the Engineer, all tracking marks, spilled paint, and paint applied in unauthorized areas.

640-3.02 Application of Pavement Markings. At the time of paint application, the pavement surface

and ambient temperature shall not be less than 50°F, the relative humidity shall not exceed 85%, and the pavement surface shall be dry. Traffic paint shall not be applied during periods of rain or if rain is imminent. Waterborne traffic paint shall not be applied if rain is expected within 4 hours after application. Paint shall be applied in strict accordance with the manufacturer’s recommendations for use. In no case shall the paint be heated above 150°F. The painted pavement markings shall be uniformly applied to the pavement surface at the minimum specified wet film thickness. Immediately following paint application, reflective glass beads shall be uniformly applied to the wet paint film at the rate of 6 lb/gal of paint. The applied pavement markings shall have clean-cut edges and true and smooth alignment. On pavements where traffic is to be maintained and the final marking pattern is known, traffic paint shall be applied before the end of the work shift. If the Contractor is unable to apply final pavement markings and traffic is to be maintained, then removable pavement markings offset from the final pavement markings shall be installed in accordance with Section 619 Work Zone Traffic Control at no additional cost to the State.

640-4 METHOD OF MEASUREMENT. Pavement striping will be measured in feet along the

centerline of the pavement stripe and shall be based on a 4 inches wide stripe. Measurement for striping with a plan width greater or less than the basic 4 inches as shown in the contract documents or as directed by the Engineer, will be made by the following method: Plan Width of Striping (inches) x Feet 4 inches No payment will be made for the number of feet of gaps in between the dashed lines. Letters and symbols will be measured by each unit applied. A unit will consist of one letter or one symbol. Examples: “SCHOOL” will be measured as six units. Double and triple headed arrows will each be measured as a single unit. The “X” in railroad grade crossing markings (MUTCD figure 263-33) will be measured by feet of 4 inch stripe.

640-5 BASIS OF PAYMENT. The accepted quantities of pavement markings will be paid for at the

contract unit price bid, which shall include the cost of furnishing all labor, materials, and equipment to satisfactorily complete the work. The cost for maintaining and protecting traffic during the painting operations shall be included in the price bid. The application of Short-Term Pavement Markings, necessitated by the Contractor’s failure to apply the required Reflectorized Pavement Marking Paints, shall be at no additional cost to the State. Payment will be made under: Item No. Item Pay Unit 640.10 White Paint Reflectorized Pavement Stripes – 15 mils Feet 640.11 Yellow Paint Reflectorized Pavement Stripes - 15 mils Feet 640.12 White Paint Reflectorized Pavement Letters - 15 mils Each 640.13 White Paint Reflectorized Pavement Symbols - 15 mils Each 640.20 White Paint Reflectorized Pavement Stripes – 20 mils Feet
