The article reveals the relationship between the concepts of "ecology", "Anthropoecology"and " architecture". The analysis of the concepts of "architecture" and "Anthropoecology", common to them, their identity, is that the object of consideration is the external environment in relation to man. It is established that the objective of Anthropoecology, in this context, is the study of human interaction with the environment, determining the conditions of its comfort and utilitarianism for humans, and the subject of architecture – the formation of the environment through the construction of buildings. The direct connection and continuity of ecology and architecture in the formation of an artificial human environment determines environmental friendliness as an essential, profound property and the mission of architecture. On the basis of comparative analysis of the concepts "Anthropoecology" and "architecture" their deep essential interrelation is established, which determines the necessity of anthropoecological approach to architectural design, as well as the transition to the integrated assessment of environmental characteristics of real estate objects.

In is paper investigated and confirmed the Deposit of bentonite clay on the studied road section of Osh-Isfana. Osh-Isfana road is an international meaning road. The road is located in the Nookatsky district of Osh region of Kyrgyz Republic and connects the two regions and gives access to the territory of neighboring States – Tajikistan and Uzbekistan. Overestimation of the roadbed with moisture is an extremely dangerous phenomenon, since the strength of the pavement and the stability of the slopes of the mounds and excavations are greatly reduced. When designing the basis of the road on collapsible soils are equally important inside the event with the aim of reducing the likelihood of soaking the soil. The recommendations on the use of local building material as a waterproofing layer of the road structure, interrupting the movement of moisture, while ensuring the removal of water from rain and snow melt.
