Abstract
Increasing the volume of crushed stone-mastic asphalt concrete used in the upper layers of road surfaces requires the development of effective stabilizing additives that ensure the uniformity of the asphalt mixture during short-term storage and transportation, as well as improving the properties of asphalt concrete. This additives include a complex stabilizing additive of the following composition: 90 % cellulose fibers from waste paper, 5 % rubber powder, 5 % viscous petroleum bitumen of the BND 90/130 brand. This article presents the results of a study of bitumen with the addition of "Viatop 66" and a complex cellulose-containing stabilizing additive (CSD). Using Fourier-transform spectroscopy, graphical data are obtained. as a result of their analysis, it is found that the interaction of stabilizing additives for crushed-mastic asphalt concrete with bitumen leads to the appearance of additional absorption bands characteristic of aromatic compounds (CH, benzene ring), sulfur-containing functional groups S=O st, R-SO-R, R-SO-OH, R-SO2-R, C=S st, as well as for C-O-H groups. X-ray spectral analysis confirmed the presence of additional sulfur-containing spectra in the composition of stabilizing additives. It is found that depending on the chemical composition of the stabilizing additives, the physical and mechanical characteristics of the bituminous binder and the resulting asphalt concrete change.

Summary
Ароматические Монозамещенные 1,2-замещенные 1,4- и 1,2,3,4- замещенные [1,2,3] замещенные. В области 1200-400 см-1 для образца No 1 969,66 см-1, 867,25 см-1, 812,82 см-1, 745,31 см-1, имеются следующие характерные полосы погло- 721,48 см-1, а также имеются дополнительные пощения: 1032,81 см-1, 964,54 см-1, 870,12 см-1, лосы поглощения: 1165,13 см-1, 1180,80 см-1, 814,56 см-1, 744,35 см-1, 722,06 см-1. В образцах No 2 и No 3 дополнительно, в отличие от образца No 1, появились полосы поглощения характерные для ароматических соединений С=Н группа, серосодержащих функциональных групп S=O st, R-SO-R, R-SOOH, R-SO2-R, C=S st а также для групп С-О-Н. 3. Полученные данные, в результате исследования химического состава «Viatop 66» и КСД методом рентгеноспектрального анализа, согласуются с результатами, полученными методом инфракрасной спектроскопии на наличие серосодержащих соединений. Для определения влияния и зависимостей стабилизирующих добавок «Viatop 66» и КСД на структурно-механические свойства битума до и после кратковременного старения применялись стандартные методы исследования, описанные в ГОСТ 22245-90, 11505-75, 11506-73, 11501-78, 33140-2014.
