Changes in south-east anatolian bitumens and their main fractions under various oxidative conditions

Fractional analyses of South-East Anatolian bitumens were made using Marcusson's method and changes in fractional compositions and in functional groups under oxidative conditions were investigated. A more detailed study was carried out on the asphaltic resins fraction of bitumen of Ma?rip origin, since, of those tested, this bitumen proved to be the most susceptible to oxidative conditions.
