ABSTRACT Various deteriorations primarily rutting occurs in hot mix asphalt under conditions of traffic, climate and environmental in length of time. To increase the resistance of mixtures and thus delaying these deteriorations, the various additives are added to the bituminous binders.

In the study, the effects of FT (Fischer Trops) paraffin, used as an additive, on the physical properties of bitumen were investigated. To this end, four different samples of bitumen/FT paraffin compositions with the modifier content, wt. %: 3, 4, 5 and 6, were prepared.

Standard binder tests (penetration and softening point) were applied to pure and modified binders. Rotational viscosity test was used to determine the viscosity of FT paraffin modified binders. The pure and modified bitumens were aged according to rolling thin film oven test (RTFOT) method. The high temperature performance levels of bitumens were determined according to Superpave system by carried out dynamic shear rheometer (DSR) test on bitumens before and after aging processes. Based on the obtained results it was determined that the G*/sinδ which is a parameter of rutting resistance increased with the increase content of FT paraffin for both aged and unaged bitumens.

The study shows that FT paraffin additive improves high temperature performance of bitumen and binder with FT paraffin can be used a larger temperature range than base bitumen.
