Abstract. The article describes conducted at the Ogarev Mordovia State University at the Department of Construction Materials and Technologies research viscous oil road bitumen, improved variety of surface-active additives, modifiers, thermoplastic elastomers and bitumen additives. The author presents the results of studies of physical and mechanical, biological, climatic and rheological properties of modified bitumen. The studies identified the optimal compositions of modified bitumen, resistant to biological degradation and climatic factors. The importance of studying not only physical and mechanical properties properties of the modified bitumen and biological, climatic and rheological characteristics of the material. We consider the development of road infrastructure in the Republic of Mordovia. It is noted that at the present time is preparing the agreement of the Office of the Republic of Mordovia highways with Ogarev Mordovia State University on cooperation on the application in the road sector of new technologies and materials, which is engaged in the development of the university. In conditions of high traffic density, and the increased load of vehicles on the roads in need of high-quality coatings is essential. Implementation of asphalt-based materials developed at the University of the Republic of Mordovia will increase the turnaround time and the quality of road works, the service life of roads, as well as reduce the cost of repairs.
