【国外标准】 Standard Specification for Preformed Retroreflective Pavement Marking Tape for Limited Service Life

This specification covers white or yellow preformed retroreflective pavement marking tapes that are designed to provide a service life of typically 3 to 6 months, on roads with up to 15 000 average daily traffic count (ADT). The tapes are intended for use as longitudinal, transverse, or word/symbol pavement markings that provide delineation day and night. The tapes may be either Type I (removable) or Type II (nonremovable). The marking tape shall be a reflective film coated with a pressure-sensitive adhesive with or without a protective liner.
