ASTM D4280-18

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D4280 − 15 D4280 − 18
Standard Specification for
Extended Life Type, Nonplowable, Raised Retroreflective
1
Pavement Markers
This standard is issued under the fixed designation D4280; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
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 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 safety, health, and healthenvironmental practices and determine the applicability of
regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
