Özet

The aim of this paper is to examine the effects of ground plastic pipe wastes on bitumen. For this purpose, three modified bitumen samples with modifier contents of 2%, 4%, and 6% along with pure bitumen were prepared and tested. To understand the effect of modifier on bitumen, conventional bitumen tests, rotational viscosity tests at 135 degrees C and 165 degrees C, dynamic shear rheometer tests at three different frequencies that represent three different traffic speeds, and bending beam rheometer (BBR) test were performed. The BBR test results showed that resistance of pure bitumen to low-temperature cracking increased by using additives up to 4%. Based on the results of this study, it can be said that waste plastic pipes can be used as modifier for the bitumen binder. The 4% additive showed the best performance.
