ABSTRACT:
A housingless abrasion resistance reflective pavement marker is disclosed. The marker comprises a housingless, flat topped body and a reflective member embeded in the body.
The body can be made of abrasion and impact resistant curable resinous filler material such as epoxy or polyester resin. The body and the reflective member can be coated with high abrasion resistance diamond like carbon film to enhance durability and retain reflectivity. The filler can be an inert additive material.
The reflective member can have light reflecting cells on its inner surface. The reflective member can be protected by a variety of abrasion and impact reducing ridges and webs. Also disclosed is a method for making housingless reflective pavement marker in an open mold.
