“…It is thus important to determine the degree of possible impacts of cryogenic processes on the road structures and foundations and to develop preventive measures to minimize the negative effects on safety of the roads in various climatic and geocryological areas. Among the important thermal physical characteristics defining the intensity of thermal processes in the road structure is the thermal conductivity coefficient of the materials used in the road construction [6,7,8]. The aim of the present research was a quantitative assessment of the influence of the extent to which pores in a gravel bedding of the road foundation are filled with ice or sand on the thermal conductivity coefficient of an ice-gravel or sand-gravel mixture.…”

Thermal resistance of the structural layers of a road is one of the important parameters that determine the choice of technical solutions of road design in the permafrost area. The purpose of this research is a quantitative assessment of the influence of the extent to which the pores in a gravel bedding are filled with ice or sand on the thermal conductivity of an ice-gravel or sand-gravel mixture. Lichtenecker formula was used to calculate the thermal conductivity coefficient of a three-component mixture. Different levels of ice content and moisture levels ofthe sand in the pores were considered. It was shown that the thermal resistance of the road structure can change significantly depending on the choice of the filler material. This allows to regulate the thermal regime of the road without adding new structural layers. The results of the calculations are presented as 2D and 3D charts to assess the influence of the filler material and the extent to which the pores are filled on the thermal conductivity coefficient of the mixture. The charts allow to see the possible changes in thermal conductivity coefficient of the structure and make a correct decision regarding the technologies to be used in construction. For example, to decide on the necessity to use a special thermal protection layer in the road structure.

Improving the performance of the gypsum binder is possible by strengthening the gypsum matrix. The increase in strength is ensured by the introduction of a complex of mineral and chemical additives. The use of waste as components of such a complex solves a set of problems. The market is saturated with competitive and high-quality materials. Designed materials meet modern requirements. In addition, the problems of waste disposal, freeing up space, environmental protection and reducing the resource intensity of production are being solved. The purpose of the work is to obtain energy- and resource-saving compositions of gypsum dry building mixtures with improved physical and mechanical characteristics through the use of modifiers from the resources of the local raw material base. The addition of basalt waste and hydro-removal ash to the gypsum binder as part of a complex of mineral and chemical additives ensures the formation of a hardened modified gypsum stone. During the research, regularities were established for the influence of the components of the additive complex on the properties of the gypsum binder. Optimal ratios between gypsum binder and modifiers have been selected. The microstructure of the modified gypsum stone has been studied. The positive effect of the complex on the structure of gypsum has been proven.
