ABSTRACT

The major objective of this study is to evaluate the influence of Rynite Polyethylene terephthalate (RPET) particles on the mechanical properties of hot mix asphalt by conducting several tests such as; resilient modulus, dynamic creep and wheel tracking test. Various RPET contents namely; 3, 5 and 7% by weight of bitumen were added to asphalt mixture using wet method. From resilient modulus test, it was found that the stiffness of modified mixtures with RPET increased compared with unmodified asphalt mixture. The improvement of stiffness for intermediate and high temperatures was between 68 % for 3% of PET, while 3.88% for 7% PET respectively. The results of dynamic creep have shown a better improvement to rutting, the 3% of RPET showed the best resistance to permanent deformation compared to control sample. The results of wheel tracking test proved that the modification of asphalt mixture with RPET improved significantly the resist to permanent deformation (rutting). The addition of RPET has good performance in hot mix asphalt.
