Recently, the Highway Bureau of the Ministry of Transport issued the "Regarding Doing a Good Job of..." 2022 Notice on Preparatory Work for the Formulation and Revision of Annual Highway Engineering Industry Standards (Jiaogongbianzi) [2022] 37 The industry standard “Technical Specifications for the Application of Mechanically Produced Sand in Highway Construction,” led by our company, has successfully been approved for development. This marks the first time our company has taken on the role of chief editor for an industry standard issued by the Ministry of Transport.
The preparation of the "Technical Code for Application of Mechanically Produced Sand in Highway Engineering" will further promote the widespread adoption and application of the reliability theory underlying mechanically produced sand technology within the highway engineering industry. The code systematically specifies the raw materials, technical performance, mix design, construction procedures, as well as quality inspection and acceptance criteria for mechanically produced sand concrete and asphalt mixtures. This will enhance the scientific rigor of China's highway engineering structural design standards and advance the development of green transportation infrastructure projects.
National ministries and commissions have introduced policies related to mechanism sand.
The project for the "Technical Code for the Application of Mechanically Produced Sand in Highway Construction" has been successfully approved, further highlighting the company’s advanced scientific research achievements and extensive engineering practice experience in the field of mechanically produced sand. Moving forward, the company will strictly adhere to relevant policy requirements, closely oversee project implementation, and ensure that the standard-setting work is completed on time, in compliance with regulations, and to a high quality. At the same time, the company will continue to deepen its efforts in key technological breakthroughs, the development of innovation platforms, and the commercialization of scientific and technological achievements, steadily advancing toward its goal of becoming an internationally renowned, domestically first-class integrated engineering technology service provider.
