INVESTIGATING THE POSSIBILITY USING CRUSHING MATERIALS OF PRODUCTION OF JSC «NIKOPOL FERROALLOY PLANT» DURING ROAD CONSTRUCTION
Abstract. Disposal of secondary materials is intended for the conservation of natural resources and the speedy maintenance of travels, as it is necessary to dispose of them in special missions. Utilization will be attracted by the countries of the European Union, in which all directives are in accordance with the provisions for managing the inputs. On the current year in Ukraine, there is no food utilization in the industry, that is why this part is located at the doorways that carry in itself a great risk for ecology, and only insignificant part is to be utilized in future events. This paper presents the results of a study of crushed stone materials produced by JSC «NIKOPOL FERROAL ALLOYS PLANT». Experimental researches on establishment of physical and mechanical properties of crushed stone of fraction of 5 – 10 mm, crushed stone of fraction of 10 – 20 mm, crushed stone of fraction of 20 – 40 mm, crushed stone of fraction of 40 – 70 mm, crushed stone-sand mix with the maximum grain size of 20 mm, crushed stone sand mixture with a maximum grain size of 40 mm, crushed stone-sand mixture with a maximum grain size of 70 mm and sand from screenings of crushing fraction 0 – 5 mm. The conformity of the studied materials to the requirements of national standards is established and the field of their application for the device of constructive layers of pavement is defined. Additional materials can be used without viscous for crushed stone spheres of road bedding (cover, base, additional basis), as well as with organic binders at the storage of asphalt concrete , black crushed stone, sums of organo-minerals from milling materials of road surfaces, which are prepared using the method of cold recycling, crushed stone-fueled sums, overgrown with inorganic knitting or a complex of knitting. Victory of pre-existing crushed stone materials for an hour of development of automobile roads to allow the change of technogenically new ones to the new environment, change of debts on the basis of victories of natural crushed stone materials and resources of vitality.
Keywords: industrial wastes, road pavement, metallurgical slag, crushed stone, crushed stone-sand mixtures.
