Abstract
Mountain and foothill regions of Uzbekistan in the winter-spring period are the subject to erosion as a result of precipitation and mudflows. This fact led to the beginning of their strengthening with gabion structures. Gabions also improve the operation of the entire structure under the dynamic influences’ action, including the seismic ones. In the work, research and testing in the laboratory and field conditions of the erected gabions effectiveness in road construction in the Parkent district of Tashkent region. The analysis of the gabion structures main structural parameters’ influence to strengthen the subgrade on their stability and deformability has been performed. Reinforcement of the road subgrade 4P187 “Kiziltof sh. - Parkent sh. (59 km) - Kumushkon” was performed with box-shaped gabion structures. This road stretch from the stake PK80 to PK90 was blurred as a result of mudflow. To strengthen this slope, a local program for its targeted strengthening has been approved. As the initial conditions for the considered site survey, the work to determine the physical and mechanical properties of soils lying in the road slope has been carried out.
Mathematical model for optimizing the repair plan for the international roughness index IRI
Authors: Aleksikov S V , Leskin A I , Gofman D I , Alshanova M I 
Published: September 2020

Abstract
The authors analyzed the existing regulatory documents and studies on the road surface evenness impact on the traffic flow speed, the transportation and traffic safety costs. Currently available methods of forming a plan of repair work are focused on the use of the roads diagnostics results according to the evenness level of the carriageway obtained with the help of thrusters. The transition to the international evenness index (IRI) requires a review of the previously obtained mathematical dependencies and existing approaches to optimizing the road network repair program. In this work, the authors established a correlation of the traffic flow average speed, losses from the road traffic accidents (traffic accidents) and the road transport costs from flatness of coverage. Based on the identified statistical patterns of changes in the IRI index, a method for calculating the road section length that requires the restoration of transport and operational indicators (TOI) is proposed. The developed mathematical model for optimizing the repair plan will make it possible to create a list of road objects taking into account their priority within the budget funding of the annual program. The proposed model is based on diagnostics and assessment of the territorial road network technical condition in the Volgograd region.
Features of landslide structures’ designing in emergency situations
Authors: Ryabukhin A K , Leyer D V , Lyubarsky N N 
Published: September 2020

Abstract
During the operation of the M-27 highway, a landslide became active on the km 56 + 680 section of the Tuapse district (Russia). As a result of the landslide masses displacement, the roadbed was destroyed and, as a result, traffic was restricted. In emergency situations, with the rocks’ continued displacements, it was necessary to develop the constructive solutions for the landslide structures in a short time. Engineering protection of roads on landslide slopes requires a detailed analysis of the source data, as well as a set of calculations to determine the designed structures’ strength and the slope’s stability. However, in emergency situations, it is often necessary to install the structures even with insufficient initial data based on a visual inspection of the site, as well as archival data. The article presents the results of a landslide site survey, as well as the results of modeling a slope with various combinations of loads. In addition, the constructive solutions of both priority measures and the main landslide control structures are presented.

Authors: Ivanova D G , Ivanova O E , Sukhinin S A 
Published: September 2020

Abstract
Sustainable development of the regional and municipal economy is possible only by increasing the economic growth rate and living standards of the population. These strategic socio-economic objectives cannot be achieved without solving the problems of gasification and gas supply to settlements. Gas supply is a technologically complex, costly and institutionally multi-stage process. The laying of gas pipelines to the places of the consumers’ localization to ensure the uninterrupted supply of natural gas in the required volume requires many significant resources, approvals and involves various economic entities and the population itself as the final consumer of gas in this process. At the same time, the use of natural gas is associated with its price, environmental and technological advantages as a fuel for the functioning of housing and communal facilities, enterprises and organizations of various sectors of the economy. In this regard, gas supply to settlements is one of the urgent tasks of both the national economy of Russia as a whole, and individual regions, and municipalities. The most effective tool for the municipalities’ gasification process is the project management, which consists in the development and implementation of specific projects for the construction of gasification facilities, designed to ensure the connection of consumers immediately after the completion of gas pipelines. In a market economy, it is project management that is able to successfully implement a set of measures for gasification of municipalities on the basis of clear coordination of actions of all participants in the process, consolidation of the necessary labor, material, financial and organizational and managerial resources, which will bring a real result, expressed in an increase in the level of gas supply to enterprises, organizations and people.

Abstract
The article examines the methodological aspects of constructing the multiplicative factorial analytical economic models that allow to systematically study the influence of the analyzed factors on the change in the total, including the material costs in the production (sale) of construction products, to identify negative trends and potential problems in the activities of the construction organizations. To implement the proper quality of constructing a complex of multiplicative factorial analytical economic models for the corporate cost management purposes in the construction industry, the requirements excluding the formal methods for constructing the models have been identified. When constructing the multiplicative factorial economic models, the expansion method, which reflects the fulfillment of the requirements established during the study for the development of such models, was used. Resulting the signs in the developed complex of multiplicative factorial economic models for the purposes of corporate cost management suggest the total costs of production (sale) of the construction products; production costs using the new (innovative) building materials; the specific total costs of production using the new (innovative) building materials, calculated per unit of the manufactured (sold) products in kind using the new (innovative) building materials; the specific total costs of the construction products manufacturing (sales) using the new (innovative) building materials as a part of the total production costs (sales) of the construction products; the material costs of the construction products manufactured using the new (innovative) building materials; specific material costs of products using the new (innovative) building materials in the total volume of production in physical terms by the construction organization (structural unit, construction project, separate type of work). The recommended set of multiplicative analytical economic models is aimed at developing the potential of economic analysis factor based on improving the information analytical database quality on the degree of the analyzed factors’ impact on the cost changes for the purpose of making the successful managerial decisions in the system of corporate cost management in construction

Construction enterprises’ marketing activities in the economic turbulence period
Authors: Khan R S , Surkov V V , Fedosenko A A , Olatalo O A 
Published: September 2020

Abstract
Construction is rightfully considered one of the most important sectors in any economic system. It takes an active part in building up the fixed assets, creating a diverse technological and social infrastructure, as well as providing the population with housing. At the same time, the specific features inherent in construction and the product it produces, such as, for example, territorial consolidation and a long service life, as well as excess of demand over the supply on the Russian housing market, allowed the construction companies to long consider marketing as an unnecessary, optional element of the market activities. However, the rapid growth observed in the field of housing construction over the past 20 years, increased the competition and increased the demands from the consumers, led to the fact that many construction companies were forced to reconsider their old attitude to marketing. Today, almost every organization in the housing market uses, to one degree or another, marketing tools, more often tactical, less often strategic. However, the ongoing changes in the Russian construction market, due primarily to economic stagnation and a decrease in the population solvency, actualize a greater active introduction of marketing tools in the construction companies’ practice, including against the backdrop of the economic activity increasing digitalization. A review of the problems and prospects in this area is one of the objectives of this article.
