Abstract: The urgency of the discussed issue: Because of poor quality of the bitumen which is let out in Russia constantly there is a search of ways of its improvement. Service life of road coverings of highways and airfields depends on it. There is a set of ways of modification of bitumens with use of various polymers, however recently the accent moves the rezinobitumnykh knitting as this way of modification not only is cheaper than the others aside, but also improves already intense ecological situation. The main aim of the study: Justification of a chemical component of process a moditsirova-niya polymeric and bituminous knitting on the basis of a rubber crumb. The methods used in the study: Need of modifying of bitumen is connected with bad operational properties of the last. For several years attempts of modification knitting a rubber crumb which yielded positive result were made. It was necessary to be defined how there is a similar improvement of properties of the final product. It was for this purpose necessary to define theoretical prerequisites of a stitching of the accompanying components, and also use of the means allowing to investigate structure of the knitting. For example: electronic microscope, spectrometer, references. The results: Technological properties of rezinobitumny knitting are caused by set: molecular coupling of particles of a disperse phase with each other in contact places where thickness of layers of the dispersive environment between them is minimum (deprived of a stability factor). In a limit case full phase contact is possible. Coagulative interaction of particles causes formation of structures with the expressed reversible elastic properties; existence of the thinnest film in contact places between particles.
