Abstract:

An end treatment was developed in this project for a previously developed low-profile portable concrete median barrier. Together, the new end treatment and the low-profile barrier provide a new barrier system for use' in low-speed (45 mph [73 km/h] or less) work zones. The end of the new end treatment has a minimum height of 4 in. (10.2 cm) which transitions into a maximum height of 20 in. (50.8 cm) in a distance of 20 ft (6.1 m). The 20 in. (50.8 cm) end of the end treatment connects to the previously developed 20 in (50.8 cm) low-profile barrier. The overall length of the new end treatment is 20 ft (6.1 m). The primary advantage of the new low-profile barrier system is that the 20 in (50.8 cm) height of the system is much less than the traditional concrete barrier height of 32 in. (81.3 cm). This reduced height of the new low-profile barrier system provides enhanced driver visibility. The enhanced visibility should provide drivers with safer conditions and should help to reduce the number of accidents in highway work zones. The performance of the new low-profile end treatment was demonstrated through a series of three full-scale crash tests. On the basis of the results of these crash tests, coupled with the results of previous tests on the low-profile barrier, the complete low-profile barrier system including the new end treatment is recommended for immediate implementation in low-speed work zones.
