The revision work for bridge prestressing industry standards has been initiated, leading the way toward standardized development in the sector.
2019-12-10
Recently, the revision of the Technical Specifications for Prestressed Construction of Highway Bridges, led by the Highway Science Research Institute of the Ministry of Transport, has officially commenced. This revision will incorporate advancements in new technologies, materials, and construction techniques within the field of bridge prestressing in recent years, aiming to further improve the standard system and guide the industry toward standardized and high-quality development. Since its implementation in 2015, the original specifications have served as a crucial technical foundation for prestressed construction of highway bridges in China. However, with the rapid development of industry technologies, certain provisions have become inadequate in meeting engineering demands under new circumstances.

According to the head of the revision working group, this revision will focus on emerging technological areas such as intelligent tensioning, prestress monitoring, and the application of environmentally friendly materials, with corresponding technical requirements and quality control standards to be added. Additionally, specialized technical clauses will be introduced to address prestressed construction of bridges in challenging environments such as plateaus, permafrost regions, and marine settings, enhancing the applicability and relevance of the standards. The revision process will extensively solicit opinions from industry experts, construction companies, material manufacturers, and other stakeholders, integrating advanced engineering practices and research findings from both domestic and international sources to ensure the scientific rigor, advancement, and practicality of the standards. The revision is expected to be completed and officially released by the end of 2025. Industry insiders have noted that the revision and refinement of the standards will further regulate prestressed construction practices for bridges, improve the quality and safety of engineering projects, drive technological innovation and industrial transformation, and provide stronger technical support for China's transportation infrastructure development.
