Polymer-bitumens modified with rubber waste, method of preparing polymer-bitumens and a modifying agent for bitumens

摘要

The purpose of the notification is to be stable in the conditions of storage and storage at elevated temperature of polymers, the way in which they are obtained and the means of modifying them to asphalt.obtained by mixing the crushed rubber waste with castor oil and contains a networking compound with its structure of reactive NCO isocyanate groups. Polymeroasflat contains a weight of polymer from 77% mass. of 95% but. asphalt and from 4% masses. dthe 20% but. rubber-oil composition and also contains from 0,25% masses. of 3% but. a networking measure in the form of a compound containing non-bound NCO isocyanate groups. The content of the fragmented rubber waste in the composition in terms of mass of polymer is 4% the mass. of 18% but.instead of castor oil from 0,25% masses. of 3% but.
