The construction of new kerbs or the replacement of existing ones is usually due to the need of installing safety or anti‐noise barriers. A suitable experimental survey has been studied and developed at the Laboratory of the University of Rome “Tor Vergata" aiming at verifying the vulnerability of the system kerb safety barrier in a bridge deck. The main scope is the analysis, through full‐scale experimental tests, of the system performances under horizontal actions simulating the vehicle derailment. Particular care has been devoted in reproducing actual geometries and materials. Furthermore, the actual elements usually installed in Italian infrastructures (roadways and highways), are adopted, in order to highlight the true damage typologies and failure modes. Both the cases of application of barriers on existing and new cast kerbs are analyzed, and two kerbs geometries, generally found in Italian bridges are cast and tested. The obtained results provide useful information on the safety check to be developed on this kind of structures.

在水平作用下对路缘进行的全面测试

新路缘石的建造或现有路缘石的更换通常是由于需要安装安全或抗噪屏障。罗马大学“ Tor Vergata”实验室研究并开发了合适​​的实验调查，旨在验证桥面系统路缘安全屏障的脆弱性，主要范围是通过全面的实验测试进行分析在模拟车辆脱轨的水平动作下的系统性能中，特别注重复制实际的几何形状和材料，此外，还采用了通常安装在意大利基础设施（公路和高速公路）中的实际元素，以突出其真实性。损坏类型和故障模式。分析了在现有和新浇筑路缘上施加障碍的两种情况，并浇铸和测试了在意大利桥梁中常见的两种路缘几何形状。获得的结果提供了有关将要在这种结构上开发的安全检查的有用信息。
