The results of using modern techniques of rehabilitation in flexible road pavements are presented. The modification of road bitumen’s using surface active additives (SAA) has been studied. The paper also discusses possible use of the "Superpave" methodology for bitumen used in road construction in Georgia, which was first performed by the scientific collectives of the USA, Canada and Europe. The implementation of the MSCR test is presented, which allows to evaluate the effectiveness of the polymer modification and the resistance of the polymer grid to the load at a specific temperature. Attention is also focused on the role of the binder in the formation of the main defects of road wear, because 60% of the formation of pavement fatigue cracks and other defects comes from the binder.
