Abstract

Since
exact behaviour of components within bitumens is not completely determined and
the absence of cooperative study related to modification of bitumens, 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. In this paper, virgin
bitumen samples were composed by using different types of polymers such as
elastomers, plastomers and polyethylene groups. For this purpose; bitumen
samples were modified by recommended content of three different polymers as
elastomer, plastomer and polyethylene polymer at concentration of 3.2%, 1.4% and
1.5% by weight of the bitumen respectively. Following the determination of the chemical
characteristics of bitumen samples by spectroscopy, resistances of fatigue deformation
levels of polymer modified bitumen were determined by Dynamic Shear Rheometer.
