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.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers nonplowable, retroreflective raised pavement markers for nighttime lane marking and delineation.
1.2 The values stated in inch-pound units are to be regarded as the standard, except where noted in the document. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 The following precautionary caveat pertains only to the test methods portion, Section 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. , of this specification:
