ABSTRACT:
A roadway marker comprises shell molded of suitable plastic and having an internal honeycomb configuration. A base plate extends over the lower surface of the shell covering the honeycomb arrangement and defining a plurality of chambers internal to the shell. The plate is provided with a plurality of apertures, each opening to a chamber. When the marker is installed, adhesive material flows through the apertures and into the chambers. Before the adhesive sets, it forms mushroomed-shaped configurations over the top inside surface of the plate. The mushroomed configurations create a strong mechanical bond between the plate and the associated roadway surface. The large lower surface area of the plate also enhances bonding of the marker to the roadway.
