3354Preformed Pavement Marking Tape

3354.1SCOPE

Provide white, yellow, white contrast, and yellow contrast retroreflective pavement marking tape prefabricated for recessed traffic marking on bituminous and concrete pavements.

3354.2REQUIREMENTS

A General Provide pavement marking tape meeting the following requirements and characteristics:

requirements in 3354.2C, “Color,” lifting, or shrinkage throughout the life of the marking

Apply the preformed pavement marking tape as recommended by the manufacturer to provide a neat, durable marking that will not flow or distort due to temperature if the pavement surface remains stable. Use Equipment and application methods specified by the manufacturer. Uniformly distribute beads throughout the polymer with strongly bonded protruding surface beads. B Retroreflectivity Provide preformed pavement marking Material meeting the minimum initial pavement marking retroreflectivity values using 30 meter geometry and meeting the testing procedures of ASTM E1710, Standard Test Method for Measurement of Retroreflective Pavement Marking Materials with CEN-Prescribed Geometry Using a Portable Retroreflectometer. Table 3354.2-1 Minimum Initial Pavement Marking Retroreflectivity White Yellow Tape 600 milli-candela/ square meter/lux 500 milli-candela/ square meter/lux C Color Provide preformed pavement marking tape meeting the following requirements:

Test a sample 6 inches by 1 inch by 0.060 inches at a temperature from 70°F to 81°F using a jaw speed of 6 inches per minute. E Elongation Provide preformed pavement marking tape with an elongation of at least 15 percent at maximum load, when tested in accordance with ASTM D638, Standard Test Method for Tensile Properties of Plastics. F Skid Resistance Ensure the surface of the retroreflective pliant polymer provides a skid resistance value of at least 45 British Pendulum Number (BPN) when tested in accordance with ASTM E303, Standard Test Method for Measuring Surface Frictional Properties Using the British Pendulum Tester . G Thickness G.1 Unpatterned Provide unpatterned retroreflective pavement marking tape at least 0.060 inches thick. G.2 Patterned Provide patterned retroreflective pavement marking tape at least 0.065 inches thick at the thickest portion of the patterned cross-section and at least 0.020 inches thick at the thinnest portion of the cross-section.

3354.3SAMPLING AND TESTING
