Statement of the problem. In order to solve complex problems in the field of road construction, the main task in the field of scientific research, which can easily and adequately develop with obtaining real results, is today the formation and development of regional road research institutes or, in extreme cases, research roadlaboratories.Results. The advantages and disadvantages of two methodologies on the way to improve the quality and durability of the main structural elements of roads (subgrade and pavement), taking into account many primary and secondary factors, are considered. One of the methodologies is quite well known and provides today the required level of quality of asphalt concrete abroad within the Superpave system. The second methodology is based on a rheological approach to improving the technology of compaction of road-building materials and little is known to road builders. Conclusions. It has been established that the development of the first methodology of scientific research in our country is very difficult, and the second is quite affordable and feasible on the basisof the formed regional research road organizations. Moreover, the concept of their formation determines the significant advantages of using the second methodology.
