“…Ductility characterizing the elastic and stress-strain properties of PBB increases at the temperature of 0 °C. The modified bitumen composition calculation program [21] can be used when selecting the PBB compositions of different brands that meet the requirements of GOST R 52056-20003 and are intended for the road construction, id est the production of polymer-asphalt concrete mixtures, surface treatments, production of polymer-bitumen emulsions. The software makes it possible to significantly reduce the labor intensity when selecting the modified bitumen compositions and to automate the calculation of polymer-bitumen binders compositions with the specified technical properties.…”

The paper presents the studies on the compositions selection and properties of polymer-bitumen binders obtained using the viscous petroleum bitumen, styrene-butadiene-styrene polymer and plasticizer according to the experimental planning method. Regression equations of the polymer-bitumen binders processing and performance properties, which make it possible to optimize the compositions and predict their properties taking into account the operating conditions, were obtained. Polymer-bitumen binders in comparison with the properties of viscous road bitumen have the increased indicators of heat resistance, crack toughness, ductility and elasticity. To obtain the adequate mathematical model, the experimental data were processed, compositions were optimized and dependence diagrams were constructed by using the Maple software package. The software for a personal computer including the algorithm and program for selecting the polymer-bitumen binders has been developed. When using the software it is possible to automate the calculation of the polymer-bitumen binders compositions with a given set of technical properties.

“…The reactivity, as well as the structure of the molecule, largely depends on temperature, so at a temperature of 110-119 °C sulfur begins to melt. When heated above 120 °C, cyclic molecules are converted into polymer chains; at 160 °С, this process begins to intensify (Galdina, 2011).…”

Currently, work on the creation and production of new composite materials capable of long-term operation in industrial, climatic and other types of aggressive environments is one of the main tasks of the airfield industry. When organizing the production of new building materials in the context of rising prices for raw materials and energy resources, it is necessary to study the possibility of replacing the traditional raw material component with cheaper, more common raw materials, while simultaneously increasing the durability of airfield construction. One of these materials is technical sulfur. The organization of the production of sulfur-containing composites – sulfur asphalt concrete and sulfur concrete will ensure the production of new materials characterized by reduced energy consumption and ensuring reliable operation in conditions of variable temperatures and aggressive environments without increasing their cost compared to traditionally used materials. A significant reduction in excess sulfur will have a positive impact on the environmental situation in the areas of its production, a significant reduction in greenhouse gas emissions in the production of sulfur composites compared to the production of existing analogues based on traditional materials.

“…Although all the mixes with rubber meet the requirements of the State Standard GOST Р 52056-2003 on elasticity, it increases significantly in proportion to the increasing percentage of rubber in comparison to the control PBB with 22% of vinyl acetate (Figure 2). Such elasticity results from the fact that macromolecules of rubber in stress-free state of equilibrium have coils, they are rolled into a spiral [21]. Under the load, the molecules straighten, in other words, initially they stretch, because it is the macromolecules that straighten and not the bonds between the links.…”

One of the ways to improve the qualities of asphalt and concrete mixes is to modify the binding agent in its composition with polymer additives. The article presents rubber with polyethylene and vinyl acetate (sevilen) as a modifying additive to the road construction bitumen. The impact of rubber on the properties of the polymer bitumen binding agent (PBBA) was analysed. The mode of action of the complex additive was explained, the evidence-based concentration of rubber in PBBA was identified.
