Scope

Main technical content: The Qinghai-Tibet Plateau is an important national security barrier and strategic resource reserve base in China. Under the strategic requirement of "governing the country means governing the borders, and governing the borders means stabilizing Tibet", and the urgent need to improve transportation infrastructure and enhance transportation service quality in Tibetan areas, highway construction in permafrost regions will witness leapfrog development. To enhance the technical level of highway construction in permafrost regions and ensure high-quality construction of highway projects, the drafting team, based on summarizing the experience and scientific research results of permafrost highway projects at home and abroad in recent years, fully referenced and absorbed relevant standards, advanced technologies, and construction experiences at home and abroad, and widely solicited opinions and suggestions from relevant units and individuals inside and outside the industry to compile this specification. This specification is divided into seven chapters, with the main sections including: 1 General Provisions; 2 Terminology; 3 Basic Requirements; 4 Block Stone Roadbeds; 5 Insulation Layer Roadbeds; 6 Heat Pipe Roadbeds; 7 Ventilation Pipe Roadbeds
