| Title of the article | Evaluation of physical and chemical features of mixed plasticizers of bitumen binders by differential scanning calorimetry |
| Abstract. | Problem Statement. The main problem of organic road binders is a significant deterioration in their properties both in the manufacture of asphalt mixtures and during the operation of road surfaces. The positive role of polymer modifiers, primarily styrene-butadiene-styrene thermoplastics (SBS polymers), is well known. However, their effective use is possible only if the required degree of swelling is achieved under the action of low molecular weight substances either from the composition of the initial bitumen or introduced additionally. The purpose of the research is to study the properties of mixed plasticizers of plant origin by differential scanning calorimetry. The objectives of the study are: to create mixed plasticizers of plant origin with different ratios of residual products of forest chemistry, as well as to evaluate their effect on low-temperature performance of petroleum viscous oxidized bitumen for road construction. Results. The study of the quantitative effect of the ratio of components in a mixture of plasticizers on their physical and technical characteristics was carried out using such commercial products as tall pitch (TP) and light tall oil (LTO). During the experiment, the method of differential scanning calorimetry was used, the research was carried out on the thermogravimetric and differential thermal analysis device. It is shown that in order to achieve the existing regulatory requirements for low temperature values of bitumen binders, it is advisable to consider a mixed composition based on the studied plasticizers of plant origin in the ratio TP/LTO = 40/60. With this ratio, the required level of low-temperature properties was achieved and increased compatibility in complex multicomponent bitumen compositions was noted in comparison with the canonical petroleum plasticizer, industrial oil, which can lead to a decrease in the temperature of bitumen brittleness and is an absolute advantage when using asphalt mixtures and asphalt concretes in the northern regions of Russia. Conclusions. The conducted studies demonstrate the effectiveness of using a mixture of large-tonnage plasticizers of plant origin to regulate the quality of bitumen binders. The expediency of using mixtures of various compositions is evaluated. The effective ratio of components for the tall pitch – light tall oil pair has been determined. |
