Abstract

Bitumen consists of thousands of different chemical molecules which are difficult to distinguish. Iatroscan method using thin layer chromatography with flame ionization detection (TLC/FID) is a comparably simple test method to characterize bituminous binder with regard to the colloidal bitumen structure in saturates, resins and asphaltenes (SARA). In a round robin test, the general precision of the test procedure was confirmed. However, especially the reproducibility of the test procedure is comparably especially in terms of the proportion of aromatic compounds. Within a sensitivity study, important test parameters were identified which will be further controlled in new RRT studies in order to improve the test precision.
