【 摘 要 】

Roads exposure to a range of natural factors, like the difference between the temperatures between the seasons between the high temperature and drought to the sharp decline in winter temperature and the impact of water and high humidity in addition to the mechanical factors, which is high load pressure and increased traffic. In asphalt binder such as cracking and crawling and the cracks of all types due to fatigue and aging due to the loss of asphalt material Association of some of its important components as the matter of bitumen is the main material bonding components of paving asphalt and therefore emerged the need to improve their specifications through additives, in this study the recycle polyethylene terephthalate of drinking water bottles by a percentage of (5%, 10%, 15%) to improve the properties of mechanical and rheological properties of asphalt and overcome pavement problems as well as the disposal of excess polymer waste and environmental pollution. Also, to the improper treatment of incineration due to the release of harmful gases such as carbon dioxide and environment-polluting chemicals. Bitumen tests such as sutures, softening point and penetration test, linear viscosity (K.V), rotational viscosity (R V) and (FTIR) spectra were studied. The result showed that of modified asphalt binder better than the unmodified.
