Crash Tests of Portable Concrete Median Barrier for Maintenance Zones

摘要

A shorter, more portable concrete median barrier was evaluated through full-scale crash tests. Test results were generally good in terms of vehicle accelerations and occupant-vehicle impact velocities. Vehicle reactions were somewhat violent, especially in the 25 degree impacts, demonstrating the severity of high-angle impacts with rigid barriers. Smooth barrier surface textures appear to be important for minimizing vehicle roll angles.
