Currently, the use of an appropriate type of binder suitable for specific climate conditions has become an important area for ensuring the operational reliability of asphalt concrete coatings. However, it is worth noting that the required set of PMB properties depends not only on the percentage of the polymer, but also on the type of plasticizer used. The results of comparative tests of polymer-bitumen binders prepared using 6 different plasticizing additives are presented. The dependence of changes in the parameters of modified binders, as well as their thermal stability, is studied. Based on the analysis of generalized efficiency criteria, a Comprehensive assessment of the effect of the plasticizer on the properties of the final product – PMB-was performed. The result demonstrates the need to use plasticizing components to achieve the required properties of the modified binder. Recommendations are given to maintain the required level of physical and mechanical parameters of PMB.
