Özet
In this study, the recycled PET is used in bitumen modification by applying a different
process in order to eliminate the phase separation problem. For this purpose, modified
bitumens are obtained by adding the triethanolamine (TEOA) chemical (wt. 2.5 %) and PET
(wt. 2, 4, 6, 8, 10 %) to pure bitumen. The properties of modified bitumens are determined
by chemical, physical, and rheological tests. According to the test results, bitumen reacts
with PET, and 6 % PET ratio is a critical value. At this ratio, the resistance of bitumen to
deformations at high and low temperatures increases significantly.
