Kostyuk M. An improvement of constructions and technologies of overhead structure of track is for modern external of railways of Ukraine environments

A research object are modern constructions of overhead structure of railway way on reinforced-concrete railroad ties at the different types of rails, different constructions of fastenings. The purpose of dissertation work is a decision of scientific task of perfection of constructions and technologies of overhead structure of track on reinforced-concrete railroad ties for the terms of the Ukrainian railways by development, ground and introduction of less dense epure of lay-out of railroad ties and application of new constructions of fastenings of claotypes. The complex method of researches is in-process used. For analytical calculations the theory of calculations of railway way was used on durability and firmness, calculation-theoretical method, theory of hauling calculations of mobile composition. Experimental methods are included by experimental tests on laboratory stands. It is well-proven that the best fastenings for track there is binding to the resilient terminals of small twigs on reinforced-concrete railroad ties. Economic efficiency of the use of the new offered constructions is certain. Results found introduction in normatively-technical editions and in patents on inventions.
