Basic Information
Scope
Main technical content: This standard regulates all aspects of road and bridge construction. In terms of basic requirements, it clarifies the responsibilities of construction, supervision, and construction units, as well as multiple systems such as quality target management. The construction preparation stage covers technical preparation, site layout, and material and equipment management, such as conducting drawing review meetings, constructing temporary facilities reasonably, and strictly controlling the procurement and inspection of materials and equipment. The road and bridge construction separately sets quality requirements for various parts, such as ensuring that the compactness of the subgrade filling base exceeds 90%. The construction inspection and acceptance divide the inspection batches, sub-items, sub-parts, and unit project acceptance standards and processes. For quality issues and accidents, it stipulates the processing procedures and standards. In addition, it makes detailed provisions on the classification, filling out, and organizing of data in construction records and reports, ensuring that the construction data is complete and accurate, and providing a basis for project quality traceability and management.
