Standard Specification for Preformed Retroreflective Pavement Marking Tape for Extended Service Life
ABSTRACT
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.
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.
