BITUMENS AND POLYMER BITUMENS - NANODISPERSE SYSTEMS
Series of Geology and Technical Sciences, 2021 This work shows the data regarding the elemental and chemical group compositions of the road bitumens. The short characteristic has been shown for the components of the bitumens - the asphaltenes, the resins and the oils. The properties have been described for the bitumens on which they have the direct impact.
