BITUMEN BINDING SUBSTANCE FOR OBTAINING LOW-TEMPERATURE ASPHALT OR COATING MATERIALS Russian patent published in 2014 - IPC C04B26/26 C08L95/00 

FIELD: chemistry.

SUBSTANCE: claimed invention relates to a bitumen binding substance, which contains bitumen and at least two additives, making it possible to reduce temperatures of manufacturing, processing and tamping temperatures of mixtures and asphalts, where the first additive represents a tall oil derivative, alone or in a mixture, and the second additive represents ester of a mixture of fatty acids. The invention also relates to low-temperature methods of obtaining the mixtures and asphalts, obtained from the binding substance, containing the additives. The invention also relates to the application of the binding substance, containing the additives, for manufacturing the mixtures and asphalts at lower temperatures and to the application of the said mixtures or asphalts, in particular, in fields of road construction, for lower layers of road coating base, layers of road coating base, foundations, upper protective layers of road coating, such as underlying layers of road coating and/or layers of road coating wear. The invention is developed in dependent items of the formula.

EFFECT: reduction of temperature of the mixture preparation with the preservation or improvement of properties.
