Introduction. Currently, the construction of highways is one of the pressing problems. In this regard, the use of foreign technologies for the construction of high-quality roads is of great importance. It is planned to introduce the principles of public-private partnership in the field of design, construction, reconstruction and comprehensive repair of public and regional highways. 118 MODELS AND METHODS IN MODERN SCIENCE International scientific-online conference A presidential decree was adopted on measures to introduce advanced foreign methods of organizing work in the field of construction and operation of highways. The resolution set priority tasks in the field of construction and operation of highways. Also, leading foreign consulting companies will now be involved in the development of the Road Construction Development Strategy. In particular, the State Committee for Investments will ensure the participation of a foreign consultant by December 30, having studied the experience of Germany. This Development Strategy is aimed at introducing modern standards and technologies in the road sector, developing programs for the construction and reconstruction of roads in 2020-2040. Main part. The government will establish a working group to establish joint ventures for the production of modern construction materials in the field of highways, to establish cooperation with German companies - "OBERMEYER Panen+Beraten GmbH", "Lahmeyer Internetional GmbH", "Lom Ingenieurgesellschaft mbH", "INROS LACKNER SE" and others - in the design of highways and artificial structures. The resolution tasked the State Committee for Roads with developing a proposal to establish a center for improving the skills and retraining of specialists in the field of construction and repair of roads by February 10, 2019. The Ministry of Finance is considering measures to introduce the principles of public-private partnership in the field of roads. It was determined that proposals for Uzbekistan's accession to the International Federation of Consulting Engineers (FIDIC) will be developed in 2019 within the framework of the current "Roadmap", which provides for the development of design and estimate documentation in the road sector, the implementation of construction and installation works, as well as taking into account volume and quality indicators when accepting them. As a result of the research, the specific features of the methods of building highways in foreign countries were identified, which are as follows: 1. Issues of organizing quality control in the construction of roadbeds; 2. Issues of improving roadbed construction technologies; 3. The use of innovative materials in soil consolidation; 4. Technologies for building foundations from local materials; 5. Technologies for the construction of road surfaces of a permeable type and their characteristics; 119 MODELS AND METHODS IN MODERN SCIENCE International scientific-online conference 6. Technologies for the construction of road surfaces using the method of laying a mixture of crushed stone and sand with bitumen in place and its characteristics; 7. Modern technologies for the surface treatment of road surfaces; 8. Technologies for the construction of cement concrete pavements and innovative materials; 9. Organization of environmental protection in the construction of highways; Quality control in the finishing of the upper surface of the roadbed and the shoulder; 10. Adva
