ABSTRACT

Since exact behaviour of waxes within bitumens is not completely determined and the absence of cooperative study related to modification of bitumens involving different amounts of waxes, the values found in the study are thought to be useful in determining which type of polymer would be better in terms of fatigue parameter for the needs of petroleum refineries. The scope of this study is to minimize the fatigue cracking within bitumens obtained from different sources. For this purpose, polymer modified bitumen (PMB) samples were prepared by using different types of polymers such as elastomers, plastomers and polyethylene groups. Following the determination of the contents of wax by Differential Scanning Calorimetry (DSC) and TS EN 12606-1, the intermediate temperature performance levels of PMB were determined by fatigue parameters.
