Modification of asphalt-free super viscous oil using ethylene copolymer with vinyl acetate

In this work the composition as well as the physical and mechanical properties of deasphalted bitumen of the Ashalchinsky field compounded by ethylene vinyl-acetate copolymer was studied. The possibility of development of an asphalt concrete pavement based on bituminous binding material, containing as dispersed phase, not asphaltene associates, but ethylene vinyl-acetate copolymer was looked into. The characteristics of the new asphalt binder are presented, on the basis of which it follows that the resulting binding material has ultra-high reserve of strength, elastic-deformation, low temperature and adhesion properties
