Abstract
Based on the comparison of the selected characteristics of laboratory prepared modified binders, different version of bituminous binders with added poly-olefin based additive (VP) alone or in combination with SBS polymer were assessed. The basic type of bitumen used for the modification was a paving grade 50/70 to which 5 M% and 6 M% or only 1 M% but in combination with a selected type of SBS (quantity of 3 M%) were added. Frequency sweep test (complex shear modulus) and MSCR test was done on virgin and aged binders. Additionally assessed binder variants were used in a SMA mixture and bitumen properties were compared with performance behavior of the mixture – mainly stiffness, water susceptibility and resistance to permanent deformations.
