About the use of use of By-Products of the Industry as a Mineral Powder of Road Asphalt Concrete
Abstract: An analysis of the literature data indicates that many powdered by-products of industry are used as a mineral powder: fly ash from thermal power plants, dolomite dust, fly ash from cement kilns, decomposed slag particles, acidic silica waste from industry, sulfur-containing waste, etc. Nevertheless, these powder products inferior in quality to limestone mineral powder. Many increase the consumption of organic binder, have insufficient adhesion to the binder, a small specific surface or, conversely, a highly developed inner surface, intensify the aging process of concrete and thereby reduce the durability of non-rigid road surfaces. In this regard, we consider it expedient in further research to consider existing methods for improving the quality of mineral powders and, above all, changing their surface properties in order to increase their density and enhance the structuring ability in concretes based on organic binders.
Keywords: road asphalt concrete, mineral powder, technogenic raw materials for the production of mineral powder of asphalt concrete mixtures.
