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.
