CONCRETE PROPERTIES IMPROVEMENT OF SLAB TRACKS USING CHEMICAL ADDITIVES

Purpose. On the Railways of Ukraine a very large number of slab tracks are operated with cracks. Many scientific works of previous years are dedicated to improving the design of slab tracks. The main causes of defects are: poor exploitation of the track; insufficient physic-mechanical characteristics of concrete; poor quality of initial materials. It is therefore necessary to develop an optimum concrete mix for the manufacture of these concrete products. Methodology. To assess the impact of individual factors and effects of their interactions on properties of concrete mix and concrete method of experimental and statistical modeling was used. At this, methodological fundamentals of mathematical experiment planning in concrete technology and modern methods of optimization of composite materials were taking into account. Based on the obtained data during the planned experiment conducting, including15 studies and using the computer program MathCad, were obtained the regression equations, which describe the relevant physical and mechanical properties of concrete. On the basis of the equations with the help of computer program MATLAB R2012b the graphs were drawn, illustrating the dependences of system response from the changes of two factors at a fixed value of the third factor. Findings. Firstly was the analysis of cracks that occur in the process of operation in the constructions of slab tracks. Further reasons of possible occurrence of these cracks were presented. In the process of the conducted research the author has concluded that for rational concrete mix development it is necessary to conduct the planned experiment with the use of quality materials. It was established that to increase the strength, chemical additives should be added in to concrete mix, it will let reduce cement amount. Originality. Experiments proved the usage of modern chemical additives in order to improve the properties of concrete. Models were developed, reflecting characteristics of concrete strength. With their help one can optimize concrete composition. Practical value.

THE CAUSES STUDY OF THE PREMATURE DESTRUCTION OF THE CONCRETE SLEEPERS ON THE ZNAMENKA TRACK OF THE IF10 OF THE ODESSA RAILWAY

Purpose. The aim of the paper is to study the factors that led to the premature destruction of concrete sleepers. Methodology. The express-method of determining the morphology and chemical composition of structural components in concrete, patented by Dnipropetrovsk National University of Railway Transport was used in the paper. Methodology makes it possible to control the morphology and chemical composition of cement crystals as the weakest link in the structure of composite material – concrete, and to predict, in accordance with the recommendations of the German Scientists, the possibility of structural transformation of cement in the solid state, which determines the durability of the composite material. Findings. The mass destruction of concrete sleepers on railways of Ukraine is becoming more frequent every year. Moreover, if such destruction in 2010 appears after 4-5 years of operation, in 2015 it is only after 2-3 years of installing the sleepers on the main railways. The nature of the destruction of concrete sleepers can be noted as malty factors influence on it. The batches of cement and other raw materials have been investigated before using with the standard methods in accredited laboratories of PAC «Ukrgeolbudm» (Kyiv) and received a positive evaluation for use in the production of concrete sleepers. However, a significant error in experimental data by standard methods not allowed revealing the critical properties of materials that adversely effect on the durability of rail base concrete. According to the research it was determined that the causes of mass destruction of sleepers are: 1) the inhomogeneity of the macrostructure of the concrete, as a consequence of the use of crushed rock of fraction 5-25 mm; 2) the impact of aggressive environment on the surface of the concrete sleepers; 3) the presence of a secondary structure of sleepers of large ettringite crystals prone to restructuring and the presence of alkaline silicic acid reaction products around the amorphous or those containing amorphous silica sand particles; 4) the exceeding of regulatory factor of the reduced alkalinity of dense and porous components of cement stone is respectively to 3.6 and 3.2 times; 5) saturation of the surface of sand particles of chlorine atoms, which are further accelerate and initiate the alkaline silicic acid reaction. Originality. The scientists firstly applied the author's proprietary express-method of studying the morphology and chemical composition of the structural components of concrete. Practical value. The application of the proposed research methodology and structure of raw materials in the concrete production cycle of enterprises will help to prevent the premature deterioration of concrete as a result of internal factors.

Formation of fuzzy support system for decision-making on merchantability of rolling stock in its allocation

The paper proposes a scientific approach to solving the problem of forming the knowledge base and effective support system for decision-making by operational railway employees in the allocation of rolling stock depending on its merchantability. Analysis of existing regulations has shown the lack of a clear and unambiguous definition of merchantability of the rolling stock in regulatory documents, so contentious issues arise between the carrier and the shipper, especially in the reallocation of the rolling stock for loading. In this regard, almost complete lack of the formalized selection technology of rolling stock for loading was revealed. The results of solving the problem of merchantability assessment of the rolling stock allow to improve the quality of management decisions, primarily through the optimal use of internal resources, and the proposed solution methods based on fuzzy DSS can be used in conjunction with other control methods. It is important that the presented approach allows a more thorough merchantability assessment of the rolling stock by reducing the uncertainty of this matter in both regulatory, and technological terms. This issue is an integral part of the range of problems that arise when forming the system of logistics centers of Ukrainian railways.

FEATURES OF THE DEFORMATION WORK OF THE RAILWAY TRACK

Purpose. The purpose of study is to identify the features of the railway track work deformation by establishing the boundaries of the track sustainability depending on the design and condition of systems of the upper and lower track structure, plan of a line for the possibility of forming a regulatory framework for reliability and functional safety of railway track in Ukraine. Methodology. The complete method of S. P. Pershyn of determination the critical values of compressive strength was used for the achievement of the purpose. Findings. The author found that the ratio of the minimum values of compressive force under the certain bending deformation can be used as evaluation conditions of the track deformation resistance and basis for formation the base of reliability and functional safety of the Ukrainian railway track. Originality. The theoretical position for the consideration the deformation stability of the upper and lower track structure were proposed. It will allow studying the process of deformation work of the system, which changes its state during a particular operating time. Thus, it allows determining the parameters of the functional reliability of the train as a part of security pass of the rolling stock on the track, accounting its technical condition. Practical value. Usually for the safe passage of rolling stock the parameters of the oscillations of the «vehicle – track» are determined. These parameters are normalized with the instructions on design and maintenance of the railway track. Changes in the regulatory framework of rail transport in recent years provide the observance of its functional safety that are not included in the existing regulations of the railway track. Therefore it is necessary the issue of effect impact assessment of the rolling stock on the track to consider as a dynamic process, limit states criteria of which are determined on the basis of existing norms, correlated with the reliability states, and to develop criteria for security throughout the life cycle on their basis. At considering the dynamic process of track oscillation and rolling stock must take into account the deformation resistance of the track. This issue was addressed only in terms of changes in temperature deformations. This study provides a basis at which it is possible to take into account the stiffness of deformation for the ability of regulatory framework formation for reliability and functional safety of railway track in Ukraine.

Institutional rail reform: The case of Ukrainian Railways

Rail reforms are aimed at increasing the share of rail in a country's or region's modal split through an efficiency improvement in railway operations, a stimulation of intra- and inter-modal competition and an increased financial accountability and sustainability of the railway company. The recent approaches to railway institutional change in the leading economies of the world was guided by deregulation and liberalization of railway transport. Rail reform in the European Union aimed at a more open market and a clear division of roles between infrastructure managers and railway operators is well documented. The reforms taking place elsewhere in Europe received less attention. This paper deals with the reform of the Ukrainian Railways taking into account the difficult economic, political, social and financial environment the country is in.We analyzed the processes of institutional change in Ukraine and the effectiveness of this institutional change for the development of Ukrainian Railways. Theoretical concepts from institutional economics were applied to map how railway administration and railway players modify existing institutional arrangements to their interests.The analysis in this paper demonstrates the place-dependent nature of changes in the institutional–organizational framework for the rail sector. The case of Ukrainian Railways supports this notion. Ukraine presents a unique case given the path dependence created by its former Soviet history, the great significance of rail in the national transport network and the role of industrial tycoons in cargo generation. We believe railway transport in Ukraine should not be exposed to shock reforms given its great importance to the national economy. However, further changes in the Ukrainian Railways institutional framework are needed to fit even better into the economic realities. We propose specific recommendations for the rail institutional framework adjustments in Ukraine.
