In the studies, the extrusion method of synthesis of foam-glass ceramic was used, which contributed to the intensification of the silicate formation process and a decrease in the consumption of the alkaline component by 1.8 times. It was found that samples of granulated foam-glass ceramic with a fraction of 5–20 mm have the required compressive strength and effective thermal conductivity, which allow their use in the construction of transport infrastructure in permafrost conditions. Considering the colossal length of the Arctic zone of Russia, the perspective of the proposed approach is the possibility of creating mobile complexes for the production of heat-insulating material near the construction of highways.

Mechanisms and procedures for strategic management of the development of transport infrastructure in a large-scale region located in difficult climatic and geographical conditions are proposed. These mechanisms and procedures are illustrated by the example of managing the development of transport infrastructure in Siberia, the Far East and the Arctic zone of Russia.

The transport accessibility of the Arctic zone is of strategic interest for Russia from the point of view of the possibility of mineral exploration and ensuring further systemic development of this part of the national territory.The objective of the study is to carry out a spatial analysis of the transport system of the Republic of Sakha (Yakutia), to identify its topological properties and restrictions that impede providing sufficient logistics services. Based on the method of spatial analysis, the conducted study of the state of the transport system of the Republic of Sakha (Yakutia) allowed to assess transport provision within its territory for three types of transportation: transport provision of internal regional (local) transportation, transport provision of accessibility (entry and exit) of the territory of the region, and transport provision of transit transportation across the region.The study showed that air transport is the main mode for passenger transportation, while seasonal water and winter road transportation are the main modes of freight haulage.The regions of Yakutia with access to traffic arteries and isolated from them have been identified. Calculations based on the Engel’s coefficient allowed to proceed with a mathematical assessment of the transport system of the region, which indicates its insufficient development due to the lack of year-round transportation routes in the areas of the Far North and the Arctic zone. The transport infrastructure of this part of the region are represented by seasonal winter roads and waterways, which prevents from assessing their general year-round potential. For its assessment, it is necessary to consider seasonal availability of each individual section of the network.

The article deals with the development of Arctic entrepreneurship in the Russian Federation. The development of the Arctic territories at the present stage is of increased interest to almost all world powers, since the Arctic region is becoming of strategic importance for strengthening the national security of states, so this issue is paying attention to both russian and foreign researchers. The main indicators of small business development in the Arctic zone of the Russian Federation are analyzed. It is concluded that small business is developing unevenly across the Arctic regions of the Russian Federation. According to the level of small business development, there are two groups of territories. The first category includes the Nenets autonomous district, Yamalo-Nenets and Chukotka autonomous districts, where the development of the business sector is significantly lower than in other regions. The second group includes the Krasnoyarsk territory, Murmansk and Arkhangelsk regions, where Arctic entrepreneurship is well developed. This division explains the features of small business development, taking into account the natural-climatic, geographical and socio-economic features of the Arctic territories. Proposals aimed at the development of Arctic entrepreneurship and Arctic territories are formulated. Entrepreneurship in the Arctic zone is a necessary condition for the development of these territories. It is necessary to create small mobile points for the delivery of essential goods and services, provide services in the field of cultural and educational activities, provide additional educational services, and develop social and transport infrastructure. An important direction for the development of Arctic entrepreneurship can be an innovative sphere aimed at the production of goods and services that increase energy conservation. Additional measures are required to support entrepreneurship in this area, including programs for the development of business of indigenous minorities.

The construction of transport facilities in the regions of the Extreme (or Far) North and the Arctic Zone is a very specific task with plenty of peculiarities. This can be referred to ever-frozen subsoils, hard-to-reach areas, low temperatures most of the year, as well as limited reserves of inert materials (stone, construction sand) used for construction.
