New Bitumens Obtained from Physical Distillation of a Conventional Bitumen Mixed with EVA Copolymer

Bitumen phases separated from 5% and 12% EVA/bitumen blends are investigated. Basic characterization is carried out using a peculiar thin layer chromatographer, the Iatroscan. The rheological and technical analysis lead us to conclude that these macromolecular materials, obtained from physical distillation of the blends, constitute new bitumens of unique properties.
