Abstract:

The study aimed to recycle plastic waste (water bottles) to manufacture sustainable partition blocks. The waste was recycled mechanically and chemically. The sample manufacturing process included two steps. The first was mixing recycled waste with bitumen to produce improved bitumen. As for the second step, mixing this improved bitumen at a rate not exceeding  20% with sand and gravel, at a rate not exceeding 80%, in different grades...  Among the most prominent results that emerged with us.

There are very moderate compressive mechanical properties, in addition to high sound insulation due to the small plastic particles that have penetrated the mixture, increasing the amount of insulation, in addition to high moisture insulation, since plastic and bitumen have very high insulation 

After the discussion committee recorded its observations on the thesis, which were divided between explanation and correction, and the student’s defense of her thesis, and the end of the discussion, the committee sat down to evaluate the thesis, and decided to grant the student a doctoral degree with a pass grade.
