Two very different aggregates were used as bitumen substrates: granite and dolomite. Three different phases make up granite: feldspar, mica and quartz. While quartz consists solely of silica (SiO2), micas (such as biotite) are generally composed of magnesium, titanium and iron ions. Feldspars, meanwhile, can contain potassium (orthocrystals KAlSi3O8), sodium (albite crystals NaAlSi3O8) or calcium (anorthite...
