Abstract

It is indicated that one of the reasons for the formation of defects in the upper layers of the pavement may be their insufficient water and frost resistance. It is noted that this disadvantage is due to the poor adhesion of the bitumen binder to stone materials and most often adhesive additives are used to solve this problem, affecting the surface interaction of the binder with a solid substrate at the micro level. The influence of several additives of the AMDOR trademark on the properties of bitumen binders is considered. It is concluded that the results obtained reflect the effect of the selected adhesive additives on the physical properties of the modified binder immediately after modification, as well as after the short-term aging process by RTFOT.
