FIELD: consolidation of asphalt concrete courses for road pavements, slopes, channels. SUBSTANCE: dynamic action on mix layer is effected by means of vibrating roller. The dynamic action varies from trip to trip by changing the vibration frequency depending on static moment of unbalances mass, vibrating roller mass, relative driving force of vibration exciter. In the time between the roller acts on the layer, the mix is vacuumized at pressure from 5 to 10 kPa. The relative driving force of vibration exciter is determined from an equation presented in the claim. EFFECT: improved consolidation technology.
