Abstract:

Effect of adding different amount of the modern wax (F-T wax) to three bitumens such as 35/50 and 160/220 penetration grade were studied. The main objective of the experiment was to evaluate a changing in rheological properties of the bitumen with a synthetic wax before and after aging process according to RTFOT method and supported by the Multiple Stress Creep Recovery test (MSCR). The experiment was conducted by means of different types of laboratory equipment, such as rotational viscosimeter, ductilometer as well as equipment for determining basic rheological parameters like softening point temperature, penetration grade. Moreover an analysis was enriched by epifluorescence microscope observation of wax forms. The results show that the type of the bitumen had a decisively influence on aging process of the wax modified bitumen. The conducted analysis did not reveal a strong correlation between the modern wax content and aging rate of the bitumen. Additionally, the interaction between a modern wax content and a type of bitumen affected changes in breaking point temperature.
