Abstract
A housingless abrasion resistance reflective pavement marker is disclosed. The marker includes a housingless, flat topped body and at least one reflective member encapsulated in the marker's body during casting. The body can be made of abrasion and impact resistant curable resinous material filled with inert additives. The reflective member can be coated with abrasive resistance diamond like carbon film to enhance durability and retain longer reflectivity. The reflective member can have an inside surface divided into light reflecting cells. The reflective cells can be further protected by a variety of impact reducing raised ridges. Disclosed is a method for making housingless reflective pavement marker in an open face mold.
