Abstract:
A single-slope concrete median barrier (CMB) has been developed for use as either a permanent concrete median barrier or as a temporary construction zone barrier. The new barrier is designed to meet accepted criteria for the performance of longitudinal barriers. The new single-slope CMB is designed to be used in applications where the New Jersey CMB would be employed. The primary advantage of the new single-slope CMB is that the pavement adjacent to the new barrier can be overlaid several times without changing the performance of the barrier. This should help to reduce the maintenance costs associated with the use of permanent CMB's. Results of four crash tests are presented which show that the performance of the new single-slope CMB is roughly equivalent to the performance of the New Jersey CMB. These tests were conducted with the new single-slope CMB deployed in both the permanent and temporary configurations.
