This specification covers white or yellow preformed retroreflective pavement marking tape, that when applied to a road surface, will provide a service life normally greater than one year depending on the average daily traffic count (ADT). The preformed retroreflective pavement tape is suitable for longitudinal markings and transverse markings including word/symbol markings. It is designed to be a pavement marking with extended service life. Preformed retroreflective pavement marking tape shall be identified as: reflectivity Level I; Class 1, 2 or 3; skid resistance Level A, or B and reflectivity Level II; Class 1, 2 or 3; skid resistance Level A, or B. Color, dimensions, retroreflection, adhesion, skid resistance, durability, and wear resistance tests shall be performed to conform to the specified requirements.
