<p>A roadway marker comprises a shell (30) molded of suitable plastic and having an internal honeycomb configuration. A base plate (42) extends over the lower surface of the shell covering the honeycomb arrangement and defining a plurality of chambers (38) internal to the shell. The plate is provided with a plurality of apertures (50), each opening to a chamber (38). When the marker is installed, adhesive material flows through the apertures (50) and into the chambers (38). Before the adhesive sets, it forms mushroom-shaped configurations (58) over the top inside surface of the plate (42). The mushroom-shaped configurations (58) create a strong mechanical bond between the plate and the associated roadway surface. The large lower surface area of the plate (42) also enhances bonding of the marker to the roadway (54).</p> |
