Dec 09, 2021 · 3. Wet Reflective Markings and Raised Pavement Markers. Pavement marking materials may be supplemented with elements that provide retroreflectivity during wet weather - conditions. Research has identified a safety benefit to the use of wet reflective markings on freeways and multilane highways. As a result, for preformed plastic markings, the
AS 1906.3 Raised Pavement Markers (retro-reflective and non retroreflective). AS 2009 Glass beads for traffic markings AS 2445 Methods of sampling and testing retroreflective materials and devices for road traffic control purposes. AS 2700 Colour standards for general purposes AS 3554 Adhesives for raised pavement markers
In the State of New Jersey, raised pavement markers (RPMs) are used along all centerlines and skip lines, regardless of traffic volume, roadway geometry, or roadway classification. The extensive use of RPMs has raised interest in understanding 1) whether this significant investment generates variant
Place raised pavement markers immediately after the adhesive is applied and ensure proper bonding. Do not use adhesives or any other material that impairs the functional retro-reflectivity of the raised pavement markers. Provide a 30-day performance period that begins the day following written acceptance for each separate location.
Quite often, raised pavement markers are placed in areas that will receive either very low traffic or standard traffic for a short period of time. For example, in construction areas, markers will be put down and then later pulled back up. For applications like shopping cart return areas, traffic seldom affects the markers.
This document is relevant to Raised Retro-reflective Pavement Markers (RRPM’s), defined by AS1906.3-2017, as ‘A device which produces an effective point source of light at normal highway viewing distances by reflecting incident light in directions close to the direction from which is came’. This document specifies conditions in relation to:

NOKIN Series 290 Raised Pavement Markers are highly effective retro-reflective lane line enhancers in non-snowplow markets. The combination of a marker body produced in a high impact resistant thermoplastic and a high performance lens made of tough polycarbonate allows the marker to resist cracking and abrasion to provide high brightness and high
