FIELD: building industry. ^ SUBSTANCE: invention can be used in making road asphalt concrete covers and bases. Asphalt concrete mixture comprises bitumen binding agent, filling agent, mineral powder and ebonite crumbs taken in the following ratio of components in mixture, wt.-%: bitumen, 4.0-8.0; filling agent, 0-94; mineral powder, 0-8; ebonite crumbs, 2-96 being the ratio of bitumen mass and total surface of ebonite crumbs is 40 g/m2 or less. Invention provides reducing mean and real density of asphalt concrete mixture, simplified preparing mixture, reducing consumption of bitumen and expanding the raw base. ^ EFFECT: improved and valuable properties of mixture. ^ 1 tbl |
