Abstract
A reflective pavement marker of the type having a shell-like housing of synthetic resin or other moldable material with reflective end walls of light transmitting material and a filler of epoxy or other potting material. Ribbing is formed on the inner surface of the housing. The ribbing has a surface that makes an acute angle with respect to the inner surface of the housing to coact with the filler material to increase the resistance to separation of the filler material from the housing.
