Abstract:

 

In this study, polymer modified bitumen (PMB) from polyester polyols was prepared by bis(2-hydroxyethyl terephthalate) (BHET) which was obtained by glycolysis of Polyethylene terephthalate (PET) waste. The effect of polyester polyol structure on the rheological properties of PMB was investigated. Polyester polyols obtained by the reaction of various polyols and polycarboxylic acids. POL1, synthesized from BHET and adipic acid (AA), were blended with the bitumen resulting in improved stiffness, rutting resistance and fatigue performance with respect to neat bitumen. Also, the synergistic effects of the polyester polyol addition into styrene-butadiene-styrene modified bitumen (SBS-Bitumen) were investigated where this reference mixture contains SBS loading of 3 % according to the weight of bitumen. Although the addition of POL1(1.3:1) into SBS:Bitumen mixture at 3:3:94 weight ratio didn’t alter the high temperature performance grade of PMB, POL1:SBS:Bitumen exhibited higher softening point, elastic recovery and rutting parameter than reference mixture. The early stage promising results of this study indicated the potential benefits of polyester polyol as bitumen modifier. Also, this study showed that the use of BHET obtained by PET waste as a starting material for polyester polyol synthesis could be an alternative way to utilize plastic waste.
