FIELD: building industry; methods of production of the stabilizing additives for the macadam-mastic asphalt-concrete mixtures. ^ SUBSTANCE: the invention is pertaining to the field of building industry, in particular, to the method of production of the stabilizing additive for the macadam-mastic asphalt-concrete mixture. The technical result: the invention ensures the optimum temperatures and the time of laying, increased efficiency of the macadam-mastic asphalt-concrete mixture laying and compaction due to improvement of the quality of the stabilizing additive. The method of production of the stabilizing additive used for the macadam-mastic asphalt-concrete mixture production provides for usage of the substance with the fibrous structure and its granulation. At that in the capacity of the substance with the fibrous structure use the fibrous hydrosilicate of magnesium; before the granulation it is mixed with water, and after the granulation the granules are structurized on the vibrating inclined tray at the vibration amplitude of 24-26 mm high and at the vibration frequency of 230-250 per a minute with the subsequent drying. ^ EFFECT: the invention ensures the macadam-mastic asphalt-concrete mixture optimum temperatures and the time of laying, increased efficiency of the mixture laying and compaction due to improvement of the quality of the stabilizing additive. ^ 3 cl, 1 tbl, 1 dwg |
