“…Studies conducted in Japan have found that ash used in concrete (especially in large quantities) reduces frost resistance and durability [17]. The low frost resistance and durability are due to the reduced content of entrained air (by 1.5-3 times), depending on the carbon content in the ash [18]. It proves the efficiency of using ash in concrete under complex plastification.…”

The addition of fly ash from thermal power plants (TPP) and chemical additives, such as polycondensation products of acetone and formaldehyde, is an effective and economical method for increasing the strength and durability of building materials, in particular concrete. Fly ash added to the concrete and mortars at 10%–15% does not reduce their technical properties, while polycondensation products of acetone and formaldehyde plasticize and accelerate the hardening process of concrete. The study aims to substantiate the possibility of obtaining concrete on dense aggregates with a high content of fly ash through the use of polycondensation products of acetone and formaldehyde as additives, which are highly soluble in water and polyfunctional. The strength indicators were determined using standard methods. The study has shown quantitative changes in the properties of the fly ash-concrete mixture, improvement of its physical and technical characteristics, and durability of the fly ash concrete with the addition of polycondensation products of acetone and formaldehyde. In the present study, the authors determine the effect of fly ash addition on the properties of a concrete mixture, as well as the maximum possible content of fly ash that can be added to concrete to maximize certain properties required of the mixture; additionally, the same action is conducted with the addition of polycondensation products of acetone and formaldehyde concomitant with the addition of fly ash.

“…The structure of cast asphalt concrete made using bitumen reinforced with fly ash fiber from thermal power plants made in China becomes denser. This leads to a decrease in the rate of water penetration into the interface between the binder and the surface of mineral materials through the film of composite bitumen, in comparison with cast asphalt concrete without fiber [9]. Increasing the water resistance of asphalt concrete favorably affects the durability of the road surface using structured fiber from the fly ash of thermal power plants with bitumen.…”

“…However, work on the creation of the material and the technical and technological bases for the construction of thinlayer coatings from cast emulsion-mineral mixtures was stopped due to the lack of emulsion with the desired stable properties. As a result, the accumulated production experience was lost [9].…”

The introduction of new road-building materials with advanced physical and mechanical properties is the trend in contemporary civil engineering, which aims to increase the quality of road surfaces. The use of cast asphalt concrete in the upper layers of road surfaces as a replacement for layers made of traditional fine-grained asphalt concrete will not only increase the pace of construction and repair, but also the durability and quality of the road pavement. However, this method requires operational and economic optimization. Using fiber from the fly ash of thermal power plants is one of the solutions for the design of cast asphalt concrete compositions. The aim of the work is to design the optimal composition of hot cast asphalt concrete and cold cast emulsion–mineral mixtures with the use of fiber from the fly ash of thermal power plants for the construction of thin-layer coatings of highways of all categories and values; to study their properties; and to determine the feasibility of their use as reinforcing and stabilizing additives. The method of GOST 11506, namely, “Method for determining the softening temperature of the ring and ball”, with the apparatus “Lintel KiSh-20m-4” was used during the experiments. The use of standard laboratory tests made it possible to analyze the quality indicators of the materials under study and design the optimal compositions of hot cast asphalt concrete, taking into account the delamination of the mixture and the criterion of decomposition, in addition to exploring the properties of the obtained material.

Modern conditions in Ukraine require a rethinking of approaches to the formation of rights, restrictions, responsibilities, real estate accounting, and assessment of factors influencing these processes. Therefore, the article aims to identify the factors affecting the formation and use of the multi‐purpose cadaster as a multi‐level information system, which allows it to form a systemic environment and develop the theoretical and methodological foundations of the territorial development of regions. As a result, it is established that the multi‐purpose cadaster is a modern information system that forms the basis for the implementation of the European land administration system, provides land and real estate management, taking into account spatial, urban, environmental, and investment factors, and the level of stakeholder interaction at the regional level. Finally, the relevance of the research consists in the fact that military actions, the consequences of the COVID‐19 pandemic, deforming economic transformations, imbalances in regional ties, and social imbalances have a negative impact. In such conditions, the development and implementation of a multi‐purpose cadaster at the regional level are of particular importance, taking into account the impact of spatial, urban, environmental, and investment factors and European experience in implementing land relations.
