The popularity of asphalt mixes on a polymer-bitumen binder is caused by the desire to ensure the operational reliability of road pavements due to the axle load of vehicle and the intensity of traffic. In addition, the use of an appropriate type of binder has become an important direction in ensuring the operational reliability of asphalt concrete pavements, suitable for the specific conditions of the region, marked with PG. The provision of required set of properties of the polymer-bitumen
more » ... polymer-bitumen binder largely depends on the percentage of the polymer and on the type of plasticizer used. The article presents the results of comparative tests of polymer-bitumen binders with the use of six different plasticizing agents. The dependence of changes in the indicators of modified binders and their thermal stability is investigated. Recommendations are given to maintain the required level of physical and mechanical parameters of polymer-bitumen binder.
