A Truck-Mounted Portable Maintenance Barrier

A truck-mounted portable maintenance barrier is described. The barrier is designed to provide a reasonable degree of positive protection in short-duration work zones where it is not practical to use conventional barriers. It consists of a steel barrier section supported between two maintenance trucks. The barrier section is towed to the work zone on a specially fabricated transport dolly. On-site deployment can be accomplished by a crew of two men in 15 min or less. The barrier is highly maneuverable in the deployed configuration so that it can be easily repositioned as the work progresses. Three full-scale crash tests were conducted to demonstrate the impact performance of the barrier.
