Standard Specification for Plowable, Raised Retroreflective Pavement Markers

Abstract

This specification covers a type of plowable, retroreflective, raised pavement marker for lane marking and delineation. Retroreflective markers are intended for nighttime visibility. Markers shall be classified as to type, color, and intended application. The types of markers are: type A, type B, and type E. The colors of markers are: white, yellow, red, blue, and green. The intended applications of markers are: marker to be mounted in a holder, and marker to be mounted in a recess. The construction requirements for retroreflective markers are presented in details. The coefficient of luminous intensity, abrasion resistance, compressive strength, and impact strength shall be tested to meet the requirements specified. The holder ramp hardness shall be tested to meet the requirements prescribed.

Scope

1.1 This specification covers several types of plowable, retroreflective pavement markers for lane marking and delineation.

1.2 Retroreflective markers are intended for nighttime visibility under both wet and dry conditions.

1.3 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.

1.4 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

1.5 The following precautionary caveat pertains only to the test methods portion, Section 10, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use.
