The use compositions based on ash and slag waste as thermal insulation materials for road surfaces (part 2)

The paper focuses on the production of a material based on ash and slag waste. It could perform the function of a heat insulator during the construction of highways in regions with difficult engineering and geological conditions and geographically located in permafrost distribution areas including insular ones. The study aims to create a material with thermal insulation properties based on ash and slag waste from thermal power plants. The study is experimental in nature and is based on bench modeling of the process of thermal energy transfer through a flat wall. During the study, the authors obtained a mixture based on ash and slag waste from one of the thermal power plants in the south of the Transbaikal Territory. It is considered the optimal composition for creating a material with extremely low thermal conductivity which will undoubtedly have a positive effect in practical implementation as a structural element of a highway. The results obtained during the study can be used in the implementation of the decree of the Government of the Russian Federation dated August 28, 2024 No. 2330-r which comes into force on January 1, 2025.
