Abstract

As more lanes are often added to facilitate mobility in road infrastructure, the demand for effective crash barrier safety elements has grown with time. There is also a greater need for thin crash barrier configurations worldwide, which occupy less space. The goal of the current study is to develop a prefabricated textile-reinforced concrete (TRC) crash barrier that is non-corrosive and has a thin wall. A first-of-its-kind pre-fabrication procedure that completely avoids demoulding has been devised for the manufacturing of TRC crash barriers. Investigations were carried out on TRC crash barriers under static loading to determine the influential aspects such as the textile material (glass and basalt), the number of textile layers and their positioning, and the influence of different types of fine aggregates in the TRC binder. Further, factorial analysis is utilized to ascertain the individual and interaction impacts of major elements important to the development of the TRC crash barrier. Conclusions concerning TRC’s appropriateness for both temporary and long-term deployment as crash barriers are made in light of the research.

新型预制纺织钢筋混凝土防撞护栏的静态性能
随着道路基础设施不断增加车道以提高流动性,对有效的防撞护栏安全元件的需求也与日俱增。此外,全球对占用空间较小的薄型防撞护栏配置的需求也越来越大。本研究的目标是开发一种无腐蚀性、薄壁的预制纺织混凝土(TRC)防撞护栏。为制造 TRC 防撞护栏,我们首次设计了一种完全避免脱模的预制程序。对静态荷载下的 TRC 防撞护栏进行了研究,以确定影响因素,如纺织材料(玻璃和玄武岩)、纺织层数及其位置,以及 TRC 粘合剂中不同类型细骨料的影响。此外,还利用因子分析来确定对 TRC 防撞护栏发展具有重要意义的主要元素的单独影响和相互作用。根据研究结果,就 TRC 是否适合用作临时和长期的防撞护栏得出了结论。
