Bitumen (asphalt) oxidative aging is one of the prevalent causes of the pavement distresses which results asphalt pavement susceptibility to fatigue and low temperature cracking. Ultimately, aging of asphalt leads to pavement failure after years of usage. Environmental and financial issues raise demand of effective pavement materials recycling. However, aged asphalt materials re-usage is complex and specific. The idea of the research is to insert nanomaterials to aromatic rejuvenators for aged bitumen mechanical and physical properties regeneration. There are different types and chemical composition nanomaterials as products for new bitumen modification, this research focus on aged bitumen regeneration and prolonging the whole service-life of asphalt. This paper presents comprehensive literature analysis and explicit design of experiment subjected to bitumen (asphalt) ageing, rejuvenation and bitumen regeneration using nanomaterials. This innovative research allowed investigating the phenomenon of asphalt rejuvenation using nanomaterials and identifying the most appropriate rejuvenating additives in asphalt binder.
