There are some problems to find heavy hydrocarbon characteristic such as lake of method or techniques and the special hydrocarbon property. Therefore, it is important to obtain the relation to find heavy hydrocarbon characteristic analytically or by experiment. These relations help us to predict special property in different range or area. In this study tried to predict the bitumen’s molecular weight distribution by using its rheological property. This function obtained from the definition of complex modulus and phase angle for polymeric mixtures and investigated by zero relaxation time as rheological property. The result indicate that molecular weight distribution is sharp in low zero relaxation time and it’s so wide in high zero relaxation time and this means that the molecular weight of bitumen’s mixture increase by increasing the zero relaxation time and the distribution of molecular weight be wider.
