“…(Rolt, 2000) determined that the exposure time is the dominant factor for ageing, which was confirmed by (Yu et al, 2009) under UV exposure. Nonetheless, the handling and the storage conditions of the asphalt binder contribute to the ageing intensity (Mercado et al, 2005).…”

Asphalt binder ageing alters its chemical and physical properties in a manner to make it brittle and more susceptible to thermal and fatigue cracking. The ageing rate of asphalt binders depends on a combination of different factors related to their chemical composition, environmental conditions and mix design. In order to prevent ageing, anti-ageing additives are used. The selection of the optimal additive should follow an iterative process. The additive choice is made concerning each case studied. Then, the selected modified asphalt binder is short-term aged by RTFOT and long-term aged by PAV and ultraviolet (UV) weathering. Rheology performance parameters are measured by DSR and BBR before and after ageing. Consequently, ageing indices are calculated to evaluate the appropriateness of the additive. The paper discusses several findings on the rheological level accordingly to the literature. Finally, a process is proposed to harmonise the research and the engineering practices in studying anti-ageing additives effects on asphalt binders.

“…Garcia Morales et al (2004) discussed the viscous behaviour and microstructure of recycled ethylene vinyl acetate (EVA) modified with 60/70 and 150/200 bitumens. Mecado et al (2005) conducted a laboratory testing programme to simulate the effects of storage time, storage temperature, contamination and modification on G * /sin d after RTFOT ageing. Morales et al (2004) concluded that a 3.5% blend containing EVA/LDPE and crumb rubber appears to be an interesting formulation in order to obtain a better behaviour of bitumen in a wide range of temperatures.…”
