  • Patent number: 5104254
    Abstract: A track separator element for combining with other like elements to form a track separator for separating areas in which vehicle traffic flows from other areas. The track separator element is formed from a hollow body for accommodating ballasting fluid and has lateral flaps extending from its bottom base portion. The lateral flaps have deformations formed on their top surface for generating noise when a vehicle rides over them. An evacuation nozzle is connected to a hollow tube that allows the ballasting liquid to be easily emptied out of the element.
