FIELD: construction.
SUBSTANCE: invention relates to the method of repeated use of dismantled asphalts in the form of granulated material through control of higher extent of bitumen hardness in dismantled asphalt, which is specified by bitumen ageing, by means of a plasticiser, at the same time an agent is added to increase hardness in the combination. The specified system of the plasticiser and the hardness-increasing agent is added to the mixture that contains dismantled asphalt, in hot condition of the mixture.
EFFECT: increased extent of dismantled asphalt recycling in production of hot asphalt mixtures and reduction of quantity of used new material, such as mineral substances and bitumen binder.
