Abstract

After 20 years of rapid development of highway in China, the w-beam barrier is the most widely used form of barrier. Recycling and reusing of old barrier are often involved in daily maintenance and expansion project. This paper established the actual protection grade calculation model of the old W-beam barrier through investigation on old W-beam barrier. Considering previous research experience and theoretical calculation, five kinds of barrier structure are put forward which can enhance barrier protection ability. Two design schemes are selected through the computer simulation analysis comparisons and are tested through the full-scale impact test with real vehicle. Test results show that the protection level of selected two design schemes meet the level A protection requirements of the current assessment standard.
