Scope

Scope: This document specifies the raw materials, mix design, construction, and quality inspection for the filling of highway subgrades with recycled fine aggregates and industrial waste-improved soil. This document is applicable to the mix design, construction, and quality inspection of recycled fine aggregates and industrial waste-improved soil for the filling of highway subgrades in new and reconstruction (expansion) projects of all grades. Other roads may refer to this document for implementation. Main technical content: The main technical content is to convert the composite utilization of industrial solid waste and recycled aggregates into subgrade treatment materials, which is one of the effective ways to solve the problem of massive storage of the two. Industrial waste-improved soil with recycled aggregates has good mechanical properties and durability, and is a road subgrade filling material that takes into account both economic and environmental benefits. This document specifies the terms and definitions, raw materials, mix design, engineering construction, quality inspection, and acceptance of industrial waste-improved soil mixed with recycled fine aggregates, which is of great significance for improving the standardization and standardization of the application of industrial waste-improved soil and recycled aggregates in engineering projects.
