ABSTRACT:
A base unit and a delineating device for delineating traffic. The traffic delineating device comprises a base unit and a body unit extending upwardly via a first aperture in the base unit. The base unit comprises a first surface having the first aperture and a second surface having a second aperture, and the surfaces are joined together around a substantial section of their perimeters via a side wall, and the side wall together with the first surface and the second surface limits and defines an interior sleeve of the base unit. The side wall has an opening for inserting ballast between the first and second surfaces into the sleeve, and the sleeve is of suitable size and shape to hold the ballast. The ballast consists normally of tread from vehicle tires. Preferably, at least one of the first and second surfaces comprises a non-rounded portion, thereby preventing the base unit from rolling. The base unit can be easily assembled by local distributors utilizing local recyclables. The invention further provides flexibility in functional design, since the invention can match different shapes and sizes of a body unit of the device.
