Relationships between the chemistry and the physical properties of bitumen
The aim of this research was to find relationships between the chemistry of bitumen and its material properties. To reach this objective, 11 bitumen samples in different ageing states and four aggregates were investigated by chemical, rheological and adhesion-related methods. Regarding the rheological properties, the asphaltenes as well as the resins, aromatics and saturates (SARA fractions) demonstrate a strong influence on stiffness, viscosity, deformation behaviour and temperature sensitivity of bitumen. The ageing behaviour depends mostly on the asphaltenes. Furthermore, the adhesion properties of bitumen depend on the aggregate using in the asphalt mixture. Regarding the aggregates, the adhesion properties are affected by the content of silicon dioxide and the surface charge. The results of this research show some significant influences of the chemical properties on the physical, rheological, ageing and adhesions behaviour of the binder whereby the asphaltenes and the other SARA fractions play a decisive role.
