Abstract

This paper presents  values of classes PG X±Y of bitumen binder for regions  of the Republic of Armenia in accordance with the "Superpave" method, which is widely used in global road construction in the field of asphalt concrete mix design. Based on the high and low pavement design temperature temperature, pre-determined for the regions of the Republic of Armenia, the basic values of the bitumen binder  grades were obtained.In addition to the basic values, adjusted values of the high-temperature PG grade are also presented, which take into account both the traffic value (the number of standard axes during the service life) and the traffic speed.
