STABILIZING AGENT FOR THE MACADAM-MASTIC ASPHALT CONCRETE Russian patent published in 2006 - IPC C04B26/26 C08L95/00 

FIELD: building industry; petrochemical industry; the process of production of the stabilizing agents for the macadam-mastic asphalt concrete.

SUBSTANCE: the invention is pertaining to the development of the process of production of the stabilizing agents for the macadam-mastic asphalt concretes used, in particular, at making the highways coatings made on the basis of the macadam-mastic asphalt. The technical result is development of the stabilizing additive for the asphalt concrete produced on the basis of the cheaper components and capable to sorb the binding in the asphalt concrete mixtures, in particular, in the macadam-mastic asphalt concretes at the technological temperatures during storage and transportation of the asphalt concrete mixture produced in the granulated form suitable for transportation and direct injection in the macadam-mastic asphalt concretes on the sites of its application. The stabilizing additive in the form of the granules for the macadam-mastic asphalt concretes contains the organic binding and the structure-forming agent. At that the organic binding is selected from the group including tar, bitumen or bitumen emulsion and in the capacity of the structure-forming agent use the basement lint and-or the lint representing the waste of the cotton production at the following ratio of components in the composition (in mass %): the indicated waste - 60-90, the organic binding - the rest up to 100 %.

EFFECT: the invention ensures production of the stabilizing additive based on the cheaper components and capable to sorb the binding in the macadam-mastic asphalt concretes at the technological temperatures during storage and transportation.
