Description

Specifications include, but are not limited to: A. General  The markings shall be manufactured and packaged to permit storage at the manufacturer’s recommended shelf life for a period of not less than one year from the date of purchase.  Legends and symbols shall meet the applicable shapes and sizes. B. Composition  Provide retroflective pliant polymer pavement markings that consist of a mixture of polymetric materials, pigments and glass beads distributed throughout its base cross-sectional area, with a reflective layer of ceramic beads bonded to a polyurethane topcoat surface.  Provide material with a patterned surface with between 35 and 65 percent of the surface area raised and presenting a near vertical face to traffic approaching from all directions.  Ensure the channels between the raised areas are substantially free of exposed beads or particles.  Provide material that has minimal exposed beads and particles between the raised areas.  Provide preformed markings that conform to pavement contours by the action of traffic.  Provide pavement markings applied using a pressure sensitive adhesive in accordance with the manufacturer’s instructions. Provide markings that are immediately ready for traffic after application. C. Skid Resistance  Provide tape that has a surface that provides an initial minimum skid resistance value of 45 BPN when tested according to ASTM E 300. Obtain the values at downweb and at 45 degree angle from downweb. Average the two values to find the skid resistance of the patterned surface. D. Thickness  Provide patterned material that, without adhesive, has a minimum thickness of 65 mils at the thickest portion of the patterned cross-section and minimum thickness of 20 mils at the thinnest portion of the cross-section. E. Beads  Provide ceramic beads on the surface of the material that have a minimum index of refraction of 1.7 when tested according to ASTM E 1967. Provide glass beads, that when mixed into pliant polymer, have a minimum index of 1.5 when tested according to ASTM E 1967. F. Patchability  Provide film capable of being patched using the same type of material.
