T/SMHTA 005-2024 The technical standard for the application of recycled stabilized soil as the base layer in construction waste roads

Scope

Main technical content: The large-scale application of recycled construction waste materials in road engineering is an important way to accelerate the comprehensive utilization of construction waste resources. It has a positive significance for achieving energy-saving and efficiency-enhancing in road engineering construction, reducing project costs, speeding up construction, and promoting the green transformation of road engineering materials. Engineering practice shows that compared with traditional road base materials, recycled construction waste stabilized soil has the advantages of low carbon and environmental protection, economic efficiency, and convenient construction. Recycled construction waste stabilized soil has been successfully applied in many road projects in Shanghai, accumulating application experience. Recycled construction waste stabilized soil refers to a mixture made by adding solidifying agent to recycled construction waste and soil. The solidifying agent reacts physically and chemically with the soil, improving the physical and mechanical properties of recycled construction waste and soil. After mixing, paving, rolling, and curing, the performance of recycled construction waste stabilized soil meets the relevant technical requirements and can be used as road base materials. Compared with the currently widely used cement stabilized gravel materials, recycled construction waste stabilized soil effectively utilizes recycled construction waste, avoids the use of gravel, reduces mine exploitation, saves resources, and protects the environment. Construction waste is solid waste such as cement concrete, mortar, bricks, and stones generated during demolition and other construction activities. The piling and cleaning of construction waste can cause environmental impacts, and the recycling and utilization of construction waste is an important way to reduce resource consumption. Recycled materials are formed after sorting and processing construction waste.
