The article considers the energy aspect of compaction process of an asphalt concrete mixture with a smooth drum. The ratios between the compaction work and the material stress-strain state were obtained using the simplest rheological models example. To study the asphalt concrete mixture compaction process, a complex rheological model was adopted. Taking into account the obtained ratios for the simplest rheological bodies, an expression was obtained to determine the compaction specific work of an asphalt concrete mixture with a smooth drum. In the course of the compaction energy analysis, it was found that the compaction work is equal to the sum of irreversible losses for viscous and plastic deformation and the energy required to perform an elastic aftereffect.
