A two-piece, detachable traffic channelization element having an improved base element. The base element has a low profile, dome-like configuration with a ballast storage chamber. The storage chamber may be completely filled with a sand ballast and sealed in its storage condition by a cover secured to the chamber. The base element is molded of a resilient crush resistant plastic so that when it is fully ballasted, need not be ballasted again, and which low profile base can be traveled over by motor vehicles without engaging the base. The detached base, filled with ballast, can be continuously traveled on by motor vehicles, including loaded trucks, without damaging the base element and rendering it useless and the need to be replaced.
