METHOD OF ASPHALT-CONCRETE CHIPS PREPARATION FOR USE IN ASPHALT CONCRETE PRODUCTION Russian patent published in 2018 - IPC C04B26/26 C04B18/02 C04B18/30 C04B20/02 C04B111/27 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely, to building materials, and can be used in production of materials for the creation of road surfaces. In the process of asphalt-concrete chips for use in asphalt concrete production, asphalt-concrete chips with a particle size of not more than 5 mm are granulated to obtain granules of 10–20 mm in size while simultaneously treating the asphalt concrete chips with a surfactant that ensures the hydrophobicity of the resulting granulate, at the consumption of surfactant 0.2–0.3 % of the mass of granulated asphalt concrete chips.

EFFECT: reduction of energy consumption in the production of granulated material, reduction of its caking capacity.
