(Specification)Standard Specification for Extended Life Type, Nonplowable, Raised Retroreflective Pavement Markers
Standard Specification for Extended Life Type, Nonplowable, Raised Retroreflective Pavement Markers
ABSTRACT
This specification covers extended life type, nonplowable, retroreflective raised pavement markers for nighttime lane marking and delineation. Pavement markers shall undergo tests to examine their conformance with specified construction, performance (retroreflectivity), and physical property (flexural strength, compressive strength, abrasion resistance, coefficient of luminous intensity, color, resistance to lens cracking, lens impact strength, and temperature cycling strength) requirements.
SCOPE
1.1 This specification covers nonplowable, retroreflective raised pavement markers for nighttime lane marking and delineation.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 The following precautionary caveat pertains only to the test methods portion, Section 9, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
