The utility model relates to the field of compositions of recipes for asphalt mixtures, in particular to a composition of dense asphalt concrete АС16, which will find an application in road construction. The finished asphalt mixture according to the composition includes percentage participation of the materials stone aggregate from 0 to 2 mm (0/2) – 32.1%, stone aggregate from 2 to 4 mm (2/4) – 13.2%, stone aggregate from 4 to 8 mm (4/8) – 16.1%, stone aggregate from 8 to 12,5 mm (8/12.5) - 17%, stone aggregate from 12.5 to 16 mm (12.5/16) – 8.5%, rock flour – 3.8%, own dust – 3.8%, bitumen for road paving with penetration between 50 x 0.1 mm and 70 x 0.1 mm – 5.5%. An advantage of the proposed composition according to the utility model is evinced by the fact that the number of fractions increased in this way considerably optimizes the process of creating an asphalt mixture with the desired granulometric curve. In turn, this simplifies the production process and reduces its energy consumption. 1 claim |
