Understanding the bitumen ageing phenomenon: A review
TL;DR: In this paper, an overview of a number of studies related to the ageing process in bitumen, to determine the main component affecting this phenomenon is provided, and a review is presented of the in-laboratory tests used to simulate the different ageing processes (short-term ageing, long-term aging, UV ageing) that occur in the field, along with a description of the techniques currently employed to analyse what happens to the binder after ageing.

TL;DR: In this paper, the aging process induces a growth and nucleation of the asphaltene micelles with a concomitant reduction of the maltene phase, whereas the short term aging induces the formation of fractal-like micellar structures.

Influence of aging on the evolution of structure, morphology and rheology of base and SBS modified bitumen
TL;DR: In this paper, the influence of aging on the evolution of structure, morphology and rheology of base bitumen and SBS modified binders was investigated by Fourier transform infrared (FTIR), atomic force microscopy (AFM) and dynamic shear rheometer (DSR), respectively.

Chapter 14 Chemical Composition of Asphalt as Related to Asphalt Durability
TL;DR: In this paper, the authors examined the literature dealing with the chemical composition of asphalt and changes in composition during environmental aging that affect durability-related properties, and the characterization of the chemical functional types gave a fundamental approach to the relationships between asphalt composition and asphalt properties.
