5. Adhesion at the interface between aggregates and bitumen
5.1 Aggregate and bitumen analysis
Rock surfaces were analyzed using EDS and XPS spectroscopy. The first technique allows us to obtain the elemental composition of the samples over a thickness of the order of a micrometer, thus confirming their mineralogy. The second technique provides a composition on the 5 to 10 nanometer extreme surface. The area analyzed by XPS is a little larger here (corresponding to a 200 × 50 µm ellipse), but this technique is very useful for detecting certain mineralogical phase marker elements.
As shown in Table 2 , EDS analyses revealed that the dolomite sample was mainly composed of CaMg(CO 3 ) 2...
