This work, in order to improve the main indicators of oil-road bitumen, it is dedicated to the modification of polymer materials that have been decommissioned and turned into waste. For this purpose, "Baku 85/25" brand bitumen was selected and modified. After that, polymeasphaltoconcrete mixture obtained on the basis of changed "Baku 85/25" brand bitumen was prepared and its physical and mechanical properties were studied. The results of the analysis showed that by adding 3-5 mass parts of polymer waste to bitumen, it is possible to increase its viscosity by 2 times and its strength by 4 times. The obtained results show that the penetration of the prepared sample is 1.4 times higher than the standard, its elasticity is 4 times higher, and it is proved that the mixture has high deformation properties. As a result of our scientific research works, a new processing technology for the environmental protection of out-of-service polymer products was developed, polymer scraps of 0.16-0.18 mm size were purchased, and "Baku 85/25" brand bitumen was modified with this polymer scrap. Thus, the most critical environmental problem was solved and very valuable raw materials were obtained. Based on the obtained results, it was proposed to use "Baku 85/25" brand bitumen modified with polymer in the preparation of the asphalt-concrete mixture
