Abstract. This article presents the results of a study evaluating the effect of asphalt granulate and surfactant additives on emissions and the composition of pollutants in the production of asphalt-concrete mixtures. The technology of asphalt concrete reuse when preparing hot asphalt mixes at asphalt concrete plants is increasingly being used now in Russia and abroad. The presented technology makes it possible to recycle all the milled old asphalt concrete, to save energy and material resources. Quantitative data on the volume and on the composition of emissions of pollutants when preparing asphalt-concrete mixtures with the addition of asphalt granulate were obtained. The use of asphalt granulate can significantly reduce the cost of mixtures by saving transport costs, energy costs, mineral and binding materials. In order to assess the effect of various additives of surfactants on the volume of emissions generated during the preparation of warm mixtures with the addition of asphalt granulate, studies were performed under laboratory and production conditions. It is shown that the introduction of additives that reduce the temperature of preparation of asphalt concrete mixtures makes it possible to reduce the negative impact of asphalt granulate on emissions of pollutants, ensuring their reduction.
Key words: asphalt mixing plant, asphalt granulate, pollutant emissions, surfactant additives, asphalt concrete mixture. - REFERENCES
