Road construction in the mountainous regions of Nepal has not only added to the road building experience in the rugged mountain terrain but also created awareness that development of linear infrastructure in the mountainous regions requires multidisciplinary approach from social, economic, engineering, environmental, and biotechnical considerations besides substantial engineering-geological inputs. This paper tries to provide a brief account of the practices and developments in mountain-specific planning and management of infrastructure on the basis of experiences from Nepal.

We consider the problem of tactical forest management over a 5-year horizon with yearly periods. The main decisions made consider which harvest areas to cut in each period, the flow of timber from an area to each wood-processing mill to satisfy its annual demand, and which roads to build to access a harvest area not connected to the existing road network. The goal is to minimize the total transportation and road-building costs subject to budget limitations. To explore the benefits of economies of scale (EOS) in road construction, we incorporated this notion in the proposed model. Then, the efficiency of the obtained solution is compared with the model without EOS. The proposed model is a mixed-integer linear program, including several timber assortments and multiple periods. We validated the model for a realistic case in the context of the province of Quebec. The results demonstrate that consideration of EOS significantly reduces the total cost by about 5.3%. In the EOS solution, the road segments that are built every year are very concentrated in specific parts of the region, allowing a road-building company to take advantage of EOS. Moreover, this solution provides a much more efficient timber transportation plan.

Introduction. To the particular group of road materials that are applied by close technologies belong hydraulically bound mixtures, roller-compacted concrete and cold recycled cement bound mixtures. As it is known, the composition and also the technology of application of road materials both affect the choice of method for their specimens manufacturing. For the Ukrainian road building industry, only one method for such specimens manufacturing was implemented, but in the world-wide practices there exist a developed differentiation of said methods which considers a lot of factors. The paper is aimed on the analysis and issues to be resolved in that direction.General classification, analysis and criteria for selecting the standard methods for manufacturing the specimens of mixtures based on hydraulic binders.Taking into consideration the methods of compaction applied in various systems of standardization, the classification of methods of manufacturing of specimens of the specified types of mixtures was offered. A comparative analysis of methods of specimens manufacturing is performed taking into account the requirements for specimens, features of the procedure of selection of the mixture composition, conditions of specimens manufacturing and also mixture grading. Particular attention was paid to the choice of criteria for the manufacture of specimens of cold recycled mixtures, which, according to world practice of road construction, shall be subjected to the rheological properties testing.Conclusions.Accounting for the world-wide experience in road building industry, established in Ukrainian practice methods of manufacturing specimens of mixtures based on hydraulic binders used by close technologies need to be improved in order to:–provide a selective approach to the procedure for selecting the mixture composition;–realize the possibility for making specimens on the construction area;–ensure performing of tests accounting for the extended requirements for said mixtures.Keywords: hydraulically bound mixture; roller-compacted concrete; cold recycled mixtures; methods of specimens manufacturing; compaction methods

There are two technologies for road construction, e.g. an asphalt one and a concrete one, that exist in the market of road infrastructure at the moment and they both have their advantages and disadvantages [prof Jan Deja of Krakow Mining Academy, Cathedral of Building Materials Technology].The advantage of concrete pavement consists of the fact that it doesn’t require bigger financial expenditures within 10 – 20 years of exploitation (provided that necessary pavement maintenance treatments are carried out). In the case of asphalt pavement it is necessary to mill the wear off layer of the road already after 6-7 years. It leads to the question: which of these technologies should be chosen, which is better? The work hereby carries on analyses concerning a comparison of the technologies for road constructions; the asphalt one and the concrete one. Based on the analyses carried out with the use of the Hellwig method it was found that the achieved values of synthetic meters for asphalt and concrete pavements are close to each other, which may indicate that both technologies are comparable within the sectors taken for analyses in relation to accepted technological-technical and usability features.

The article proposes the method for ranking of competing alternatives for selection of the suppliers. The method assumes to take into account such criteria as price, quality, distance to the supplier, terms of payment and conditions for obtaining a material resource in the course of selection of the material resources suppliers. To confirm the effectiveness of the proposed method, a comparative assessment of suppliers’ preferences in the road-building company SibAgro LLC was carried out without considering the application of the method and conversely.

The article deals with the issues of political and economic power as well as their constellation on the market. The theory of public choice and the theory of public contract are confronted with an approach centered on the power triad. If structured in the power triad, interactions among states representatives, businesses with structural advantages and businesses without structural advantages allow capturing administrative rents. The political power of the ruling elites coexists with economic power of certain members of the business community. The situation in the oil and gas industry, the retail trade and the road construction and operation industry in Russia illustrates key moments in the proposed analysis.

Постановка задачи. Изучение предмета «Иностранный язык» в техническом университете предполагает усвоение обучающимися терминологической лексики в соответствии с выбранной специальностью. Опыт преподавания показывает, что студенты испытывают трудности, связанные с запоминанием терминологических единиц и употреблением их в речи. Использование на занятиях по иностранному языку приема обучения терминологической лексике посредством опоры на внутреннюю форму данных лексических единиц позволяет оптимизировать процесс усвоения обучающимися специальных терминов. Результаты. Проведенное исследование дает основание утверждать, что анализ внутренней формы образованных семантическим способом англоязычных терминов специальности «Автомобильные дороги» позволяет выявить деривационно-ассоциативную связь терминологических единиц с лексикой общенационального языка, послужившей основой для вторичной номинации. Данные лексические единицы в большинстве случаев представляют собой хорошо знакомые студентам слова, обозначающие части тела человека и объекты, находящиеся в его близком окружении : одежду, посуду, инструменты, явления природы, представителей животного мира и т.д. Выводы. Ознакомление студентов дорожно-строительной специальности с внутренней формой изучаемых англоязычных терминов, выявление ассоциативных связей терминологических единиц со знакомыми студентам и широкоупотребительными словами общенационального языка, а также выполнение в аудитории специально разработанных тренировочных упражнений помогают снять трудности усвоения обучающимися терминологической лексики и облегчают ее запоминание. Statement of the problem. The study of the “Foreign Language” subject at a technical university involves students’ learning the terminology in accordance with the chosen specialty. The teaching practice shows that students experience the difficulties associated with memorising terminological units and using them in the speech. Applying the method of teaching the terminology based on the internal form of these lexical units at foreign language classes makes it possible to optimise the process of learning special terms by students. Results. The research that has been carried out gives reason to argue that the analysis of the internal form of the English “Automobile roads” specialty terms created in the semantic way makes it possible to reveal the derivational and associative relations of the terminological units with the national language words which served as the basis for the secondary nomination. In most cases, these lexical units are the words that are well known by the students and indicate the parts of man’s body and the objects that are present in man’s immediate environment: clothing, dishes, tools, phenomena of the nature, representatives of the animal world, etc. Conclusion. Introducing the internal form of the studied English terms to the road construction specialty students, identifying the associative relations of the terminological units with the well known to the students and widely used words of the national language, fulfilling the specially developed training exercises in the classroom help the students to overcome the difficulties of learning the terminology and to facilitate its memorization.

Russian forest sector forms an attractive market for harvesting and logging equipment, however the position of Russian manufacturers is extremely weak. A brief overview of the current state of the market is presented with reference to the open sources. Its features are mentioned as compared to the road construction and agricultural machinery sectors. Three transnational companies dominate the Russian market of harvesting and logging equipment: John Deere, Ponsse and Komatsu. Most of the purchased equipment falls on machines for cut-tolength technology, such as harvester and forwarder. The market volume of new machines is estimated at 330–420 forwarders, 165–300 harvesters, about 30–40 feller bunchers and the same number of skidders. There were two waves in the consolidation of the position of foreign companies in Russia. The first was connected with the delivery of equipment and the development of foreign brands in Russia against the background of still high-profile positions of Russian manufacturers in the market. The second is the takeover of enterprises having a service network and reputation by diversified transnational corporations. The main strategies of the leading companies in the current situation are the export of equipment to Russia and the development of a service network. Companies do not turn to another level associated with the opening of production sites or joint ventures for the production of harvesting and logging machines. The Russian market is characterized by the absence of a strong Russian manufacturer of harvesting and logging machines, which is ready to significantly influence or actively participate in the processes of import substitution. The position of such a manufacturer is gradually occupied by the Belarusian Amkodor Holding. The purchase of new harvesting and logging machines can afford major timber companies. The main production sites of harvesting and logging machines are located in Finland, Sweden, USA, and Canada. In order to support forestry machine engineering, in addition to economic measures of stimulation approved in other sectors, it is proposed: to organize the work of scientific forest engineering centers on the base of public-private partnership with the financial support from the major vertically-integrated timber corporate groups; to stimulate the development of Russian sector-specific information technologies for harvesting and logging; to initiate the partnership with companies from the People’s Republic of China to launch the design and production of new-generation harvesting and logging machines.
