Abstract
The invention relates to anhydrous bituminous products containing one or several specific additives which make it possible to substantially reduce a temperature for producing aggregate and bituminous product mixtures in such a way that it ranges from 20 to 40° C., wherein the temperature of the aggregate and the bituminous product mixture during spreading ranges from 10 to 40° C. and the temperature in the core of the aggregate and bituminous product mixtures during compacting can be raised to 50° C. without degrading the standardized properties of the bituminous product and the bituminous product and aggregate mixture and ensuring the process continuity from transport to compacting according to the state of the art. The inventive aggregate and bituminous product mixtures are particularly suitable for tightening, building and servicing road surfaces, pavements and airfield runways.
