Bitumen properties are traditionally determined by means of dynamic shear rheometer measurements. In this work, we aim to demonstrate that atomic force microscopy (AFM) can be a powerful complementary tool to the characterisation of bitumen. In particular, we compare the mechanical properties of pure and modified bitumen. Two different anti-oxidant additives were used: PPA (poly-phosphoric acid) and LCC (cashew nut oil) at concentrations of 1% and 2%, respectively. We will show that the AFM technique is able to distinguish the effects of both additives in the morphological and micromechanical properties of bitumen films.
