Recently, the velocity of vehicle in highway has been increased due to improved driving environment. Unfortunately, the impact resistance of present concrete median barrier is not enough for increased impact severity due to increased velocity, furthermore, these increased velocity occurs another secondary accidents due to the concrete fragmentation. Therefore, in this study, the evaluation of impact resistance for developed concrete median barrier was performed with shock absorber.
