METHOD OF OBTAINING AND COMPOSITION OF ACTIVATED REINFORCED MINERAL POWDER Russian patent published in 2015 - IPC C04B26/26 C04B20/02 C04B14/28 C04B14/40 C04B16/06 C04B111/20 

FIELD: chemistry.

SUBSTANCE: in method of obtaining activated reinforced mineral powder for asphalt concrete mixture mineral component in form of carbonate rock, water-repelling agent - fatty acid with melting temperature not higher than 85°C, reinforcing additive in form of fibres are milled together in centrifugal mill with the following component ratio, wt %: said water-repellent 0.1-5.0; fibres 0.5-15.0; carbonate rock - the remaining part. Activated reinforced mineral powder for asphalt-concrete mixture contains homogenous mixture of milled mineral component in form of carbonate rock, mainly of cubical shape, reinforcing additive in form of loosed fibres and water-repellent in form of fatty acid, uniformly distributed on the surface of mineral component and reinforcing additive, with the following component ratio, wt %: said water-repellent 0.1-5.0, fibres 0.5-15.0; carbonate rock - the remaining part. Invention is developed in dependent items.

EFFECT: technology simplification, improvement of exploitation characteristics, increase of ecologically safety.
