Abstract
The study aimed to solve the problems of hot asphalt mixture represented by the Rutting (depth of rutting) occurring in Iraq by adding depolymerized polyethylene terephthalate (DPET) with bitumen to produce developed bitumen, while conducting the necessary tests, and after mixing the aggregate with the filler material and modified bitumen, a test of Marshall stability and percentage of Air voids, rutting depth, and indirect tensile strength. The results reached a clear and significant improvement due to the presence of functional groups represented by monomers in the additive with the developed bitumen. The optimal percentage of the additive was 20% DPET.
