Channelizer markers are intended to supplement temporary retro reflective pavement markings for two-lane, two-way operations. Approved Products are listed in the Materials Approved Products Listing Enterprise (MAPLE).
Acceptance of channelizer markers will be on the basis of manufacturer and brand name approval and satisfactory field performance.
Manufacturer and brand name approval will be based on preliminary inspection and testing of samples submitted by the manufacturer to the Office of Materials.
Sample shall consist of one marker and the adhesive for installation along with literature describing the marker and its installation.
Channelizer markers shall have two yellow reflective lenses on each side that face traffic with a minimum size of 0.5-inch by 3.75-inch (12.5mm by 95mm) for each lens that shall provide reflectance from approaching headlights. The channelizer markers shall be made of yellow plastic with nominal dimensions of 2.5-inch height by 7.5-inch depth by 13-inch width (60mm by 190mm by 330mm).
Approval of channelizer markers may be withdrawn because of deficient monitor test results; product changes made after original approval, or unsatisfactory field performance.
The Office of Materials may sample and test channelizer markers to verify compliance with specifications.
