FIELD: building materials industry, more particularly road and aerodrome construction. SUBSTANCE: asphalt-concrete mix is prepared by mixing heated mineral materials with distilled oxidized and unoxidized shale resins having conventional viscosity of 7-45 s at 80 C and subsequently maintaining the mix for 0.5-2 hours. EFFECT: wider range of binders used, simplified preparation technology and lower temperature sensitivity of the resulting asphalt concrete. 1 ex, 1 tbl
