(Specification)Standard Specification for Preformed Retroreflective Pavement Marking Tape for Extended Service Life
Standard Specification for Preformed Retroreflective Pavement Marking Tape for Extended Service Life
SCOPE
1.1 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).
1.2 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.
1.3 The values stated in SI units are to be regarded as the standard.
