What is it about?
This study aims to establish a standard sample preparation method based on microcosmic morphology. The microcosmic morphology of polymer-modified bitumen was also quantitatively analyzed.

Why is it important?
Analysis of microcosmic morphology is significant to the quantitative performance evaluation of polymer-modified bitumen. Diverse methods to prepare observation samples have been used by many scholars but a standard method has not been established.
Perspectives
Four key technical problems should be introduced into fluorescent analysis of PMB, including sample preparation, images capture and processing, morphological quantitative characterization, and their application in performance evaluation. Obviously, sample preparation is the foundation of microstructure evaluation. But study results mentioned above mainly focus on prediction models establishment, ignoring the effects of this step on microscopic results.
