Abstract
The article discusses the asphalt concrete mixture compaction process with a road roller. The rheological model of a smooth drum and material interaction is adopted. The relaxation process that occur in the asphalt concrete mixture during compaction has been studied. During dynamic modeling, the physical and mechanical characteristics of the compacted material influence on the behavior of the latter during relaxation was established. The article reveals the relaxation process physical essence, which plays an important role in the material compaction. The law of asphalt concrete mixture behavior during relaxation was determined. The obtained dependencies make it possible to evaluate the effectiveness of the force effect of a smooth drum on each pass of the roller.
