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.

Abstract: A traffic channelizing device has a base unit made from the sidewalls of used tires, and additional tire components such as tread portions or other sidewalls, at least partially secured between the sidewalls. Tread portions may be wound spirally between opposing sidewall portions, or horizontally-arranged sidewalls may be positioned partially between the opposing sidewall portion, and may be cut and shaped to a non-circular inner shape to accommodate barrels which have a non-circular shape. Wire ties or the like are used to bind the sidewalls to produce an irregular exterior shape, so that the devices are not inclined to roll when overturned. The base separates readily from the barrel in the event of an impact.

Abstract: A traffic channelizing device has a base unit made from the sidewalls of used car or other vehicle tires, using tread portions as a stabilizer between two sidewalls, wound spirally and having an outer band with a protruding loop which results in the resilient integral base unit having a significantly reduced propensity to roll when the device is overturned. The device has the advantages of being highly resistant in wind and impact, yet being readily removable and stackable with substantially less manpower and transportation space than for existing devices. If the central hole for the upper sidewall portion of the base unit is larger than that for the lower sidewall portion, the device retains the traffic safety feature of the base being separable from the body portion in the event of a high impact, even where the upper portion comprises more than one sidewall.

Abstract: A plastic road barrier has an elongated base portion having an open center portion and a hollow peripheral portion surrounding the open center portion. The hollow peripheral portion has an inlet into an upper portion thereof for receiving water or other ballast, and an outlet from a lower portion thereof for draining the ballast. An elongated hollow upper portion, open at the bottom, extends upwardly from the base portion, and is preferably but not necessarily integral therewith. Its horizontal dimensions reduce from bottom to top, via steps and/or by being tapered, so that the barriers can be stacked by inserting the upper portion of one barrier a substantial distance into the upper portion of another barrier.
