Development of Low Maintenance Cost Median Barriers with Enhanced Safety Features

Median barriers are used as a separation between two opposing traffic lanes on divided highways. Typically, rigid median barriers are made of reinforced concrete using safety or single slope profiles. These barriers are positively constructed as an integral part of the roadway through starter bars or other construction means. A damaged rigid median barrier typically require lane closures, which results in congestion in addition to the costs associated with the repair of the damaged section. The Research Team will design a new generation of median barriers for Texas Department of Transportation TxDOT through computer simulation and state of the art optimization technologies in order to maximize the performance of the barrier in terms of safety, while incorporating low-maintenance cost features in the design. The Research Team will review traditional and non-traditional construction material and technologies for use in this new design. Full-scale crash testing will be conducted according to the latest version of American Association of State Highway and Transportation Officials (AASHTO’S) Manual for Assessing Safety Hardware (MASH) standards to validate the crashworthiness of the system.
