• Abstract:
  Median barriers are used on high-volume, high-speed traffic facilities to prevent errant vehicles from crossing a median and conflicting with the opposing traffic stream. A secondary function for some designs of median barriers is to minimize the glare of opposing headlights. The cast-in-place Concrete Median Barrier (CMB) has proven to be an effective and economical barrier in Texas and other states. Investigation into the use of a precast concrete median barrier stemmed from the interest involved in utilizing a barrier to be prefabricated concurrently with roadway construction. This more effective utilization of work force as well as early project completion and acceptance could provide measurable potential savings to both contractor and the State. In addition, when this barrier is installed on existing facilities the traffic may be disrupted for a considerable period of time if it is cast-in-place.
