Static Behaviour of a Novel Prefabricated Textile Reinforced Concrete Crash Barrier

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.
