| Title of the article | Improvement of soils by fly ash in structures of retaining structures of roads |
| Abstract. | Setting the task. In this paper, the urgency of the problem of waste disposal from solid fuel combustion is indicated. Due to the continuous process of fuel processing, a huge amount of waste is generated, which is not recyclable and is stored in landfills, occupying a significant area of free and potentially usable territories. The purpose of the work is to study the possibility of using ash and slag waste (fly ash) from the Reftinsky state regional power plant in road construction. To achieve this goal, the following tasks were solved: assessment of the chemical composition of the fly ash of the Reftinsky State regional power plant from the point of view of danger to human life and the environment; analysis of the stress-strain state of the retaining wall structure with backfilling from the soil improved by fly ash. Results. The assessment of fly ash as a material that is a waste of fuel processing at the state regional power plant has shown that fly ash does not pose a danger to human life and the environment if ash is used in various human activities. The effectiveness of the use of fly ash (namely, fly ash from the Reftinsky State Regional power plant) has been proven by conducting numerical experiments that illustrate the improvement in the design of the retaining wall and soil. Conclusions. The significance of the results obtained for road construction lies in the fact that the use of secondary resources, industrial waste, reduces the need for road construction materials and increases the efficiency of their use. The use of fly ash will potentially help to increase the volume of ash waste disposal at landfills and improve the environmental situation in the regions of the Russian Federation. |
