Thermal history-induced nanoscale surface characteristics of bitumen: implications of sample preparation on accurate characterization

Key Points

• Nanoscale surface characteristics were significantly affected by thermal history, defining bitumen properties.
• Surface analysis revealed that incorrect sample preparation led to mischaracterization of bitumen's true properties.
• Analysis of bitumen samples was conducted using advanced microscopy techniques to assess surface characteristics.
• Highlights the importance of standardized sample preparation methods for accurate characterization of materials.
