FIELD: chemistry.
SUBSTANCE: invention relates to the industry of construction materials, asphalt mix and a method for preparation thereof. The asphalt mix contains mineral material which contains crushed rock, fine aggregate, mineral powder, as well as asphalt binder and reinforcing fibrous filler, with the following ratio of components of the asphalt mix in wt %: crushed rock - 30-70, fine aggregate - 10-65, mineral powder - 5-40, asphalt binder - 3-15 (over 100% of mineral material), 0.1-0.15 wt % PAN fibres and 0.01-0.15 wt % carbon fibre (over 100% of the weight of mineral material). The carbon fibre in the mixture is finely cut carbon fibres with length of 3-40 mm from continuous carbon fibre having monofilament breaking strength of not less than 2.5 GPa. Also described is a method of preparing the asphalt mix.
EFFECT: high resistance to rutting and formation of quality and durable asphalt coat.
