RCAT Short-therm ageing of bituminous binders in presence of mastic
Original language description
The resistance of bituminous binders to ageing is one of the main factors influencing the lifetime of pavement. During the pavement construction and lifetime the bituminous binder oxidizes, which has a negative effect on the pavement durability. The first phase of ageing process includes rapid short-term ageing that occurs during production, storage and field application of a binder. The second phase of ageing process is slow and long-term ageing during the whole pavement lifetime. Several methods are used in laboratory scale to simulate the ageing of bituminous binders. In this study, short-time ageing of bituminous binders was performed using methods RTFOT, RCAT, and mainly RCAT with mastic at standardized temperature of 163 °C. The method RCAT with mastic should be closer to real conditions in the asphalt plant compared to the standard RTFOT or RCAT methods, because the mastic can influence the reaction mechanisms during oxidation. The influence of mastic on the bitumen ageing was studied by comparison of the results from ageing with and without mastic, using two neat bituminous binders.
