METHOD OF PREPARING POLYMERIC BITUMEN COMPOSITION Russian patent published in 2000 - IPC

Abstract RU 2144049 C1

FIELD: highway engineering, preparation of roofing materials, hydroinsulations and sealing compounds. SUBSTANCE: method comprises adding, under agitation, polymer to heated bitumen. Agitation is carried out in rotor pulsating device which maintains hydromechanical and acoustic effect within radiated frequencies ranging from 0.2 to 36 kHz at acoustic effect power of 90 to 125 Db. Polymer is added both in pure foam or as solution in organic solvent, and bitumen is heated to temperature not lower than softening temperature thereof. EFFECT: higher elasticity, greater adhesion and tensile properties of the polymeric bitumen composition. 4 cl, 3 dwg, 1 tbl
