Abstract

Inverse gas chromatography (IGC) was used to characterize two bituminous binders (A and B) of different origin. Glass transition temperatures (Tg) were determined by constructing van't Hoff plots using n-pentane probes in a temperature range between −50 °C and +120 °C. Tg values were specified using the first deviations from linearity observed in the adsorption zone of the plots. A 6 °C difference in Tg was found between the two different specimens. Retention measurements using n-alkane probes, carried out at −30 °C, revealed a higher dispersive surface energy term ( ) for bituminous binder A than for B, with values of 59.3 and 50.6 mJ/m2, respectively. Binder A was composed of a higher asphaltenes content compared to binder B. This difference in chemical composition accounted for the different surface energy values.
