A roadway marker base (10) is provided having a generally planar bottom support surface (16) with an array of downwardly facing open chambers (12) molded therein. Deformations (18, 19, 26, 46, 48) are formed on the bottom surfaces of at least some of the walls (14) dividing the chambers (12), and also preferably in the peripheral support surface (16) of the marker base (10) to provide additional downwardly facing surface area to mate with an adhesive material used to adhere the marker base (10) to a roadway surface. These deformations may be characterized by a variety of surface shapes, such as arcs (18, 19), rectangular notches (46), and dovetails (48). In the preferred embodiment, chamber walls (14) include outwardly directed lips (26) to engage the adhesive material. In another embodiment of the invention, a wire mesh (62) covers at least some of the bottom surface of the marker base (10), and is imbedded within the bottom surface of the chamber walls (14) and peripheral support surface (16). The mesh (62) engages with the adhesive to provide a strong means of anchorage. <IMAGE> |
