摘要：

Bitumen used for the construction of road pavements should exhibit adequate resistance to loads at high operating temperatures. An effective method of improving the properties of bitumen is their modification. To evaluate the high-temperature properties of bitumen, standard consistency tests and advanced rheological tests under dynamic load are conducted. The main purpose of the article is to assess the high temperature properties of modified binders produced by two major Polish producers. The assessment was based on the tests results of modified binders in the range of the standard softening point temperature test and tests in the dynamic shear rheometer (DSR) according to the requirements of Strategic Highway Research Program (SHRP) and Multiple Stress Creep Recovery Test (MSCR). It has been shown that due to the highest operating temperatures of road pavements in Poland, produced bituminous binders meet the requirements of resistance to permanent deformation with a great reserve.
