Abstract

<p>The regulation for countermeasures against rockfall disaster has been revised focusing on the safety of road traffic. If the national disaster occurred, it may be important to ensure the road network against the disaster to save people’s lives and to keep the logistics network. Therefor at first the construction limit area of roads must be protected from falling rocks as far as possible. To accomplish this, some kinds of traffic facilities were installed along the highway networks. In this paper, a low deflection barrier was developed and its applicability was verified based on the full-scale impact loading tests fallowing the design guidelines. Here, outline of the structural details and experimental results were introduced.</p>
