A single-slope concrete median barrier has been developed for use as either a permanent concrete median barrier or as a temporary barrier. It is designed to meet accepted criteria for the performance of longitudinal barriers and to be used in applications in which the new jersey concrete median barrier would normally be employed. The primary advantage of the new barrier is that the pavement adjacent to it can be overlaid several times without changing the performance of the barrier. This should help to reduce the maintenance costs associated with its use. The performance of the new barrier is documented with the presentation of results from four full-scale crash tests. These tests were conducted with the new single-slope concrete median barrier deployed in both permanent and temporary configurations.
