The aim of this paper is to describe the effect of dosing different amounts of RAP into asphalt mixtures with polymer modified binder on the change of physical properties of these mixtures. The changes in stiffness moduli, phase angles and low temperature properties of selected asphalt mixtures as a function of the amount of RAP dosed are described. The measurements were carried out on test specimens of laboratory produced asphalt mixtures AC 11 wearing course with different asphalt binders. The reference mix contained the most used road asphalt 50/70 in the Czech Republic. In addition, mixes with polymer modified binders 45/80-65, 45/80-80 and 45/80 RC were used. The dosage of R-material in the asphalt mixtures was chosen in the amounts of 0 %, 30 % and 50 %, thus describing the boundary conditions of the currently valid technical regulations and at the same time describing the physical properties of mixtures with an excess amount of RAP.
