The hazards of plastic waste (PW) from polymers (e.g., polyethylene terephthalate (PET), high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyvinyl chloride (PVC), nylon, polystyrene (PS), etc.), the mechanism of its spread in general, and its ubiquity in our daily lives as a continuously and/or frequently expelled product are a crisis of the twenty-first century, as reported by the United Nations in 2019, especially after the outbreak of the COVID-19 pandemic. This research included the process of modifying the rheological properties of asphalt to obtain asphalt suitable for use in a high-humidity atmosphere. The Iraqi climate is characterized by heat that reaches the point of harshness in the summer and coldness that falls below zero on some winter days. From this point of view, our recent study focuses mainly on making rheological and chemical modifications to asphalt using spent polymeric materials and used lubricating oils (ULO), thus achieving two important goals, namely obtaining asphalt with rheological properties resistant to the Iraqi atmosphere as well as eliminating both solid and liquid environmental pollutants. The microstructure and morphology of the designed patches were characterized using scanning electron microscopy (SEM) to indicate phase composition.
聚合物产生的塑料垃圾（PW）（如聚对苯二甲酸乙二酯（PET）、高密度聚乙烯（HDPE）、低密度聚乙烯（LDPE）、聚氯乙烯（PVC）、尼龙、聚苯乙烯（PS）等）的危害、其在一般情况下的传播机制以及作为持续和/或频繁排放的产物在我们日常生活中的普遍存在，是21世纪的一场危机，正如联合国在2019年所报告的那样，尤其是在新冠疫情爆发之后。这项研究包括改变沥青流变特性以获得适用于高湿度环境的沥青的过程。伊拉克气候的特点是夏季酷热难耐，有些冬日寒冷刺骨。从这一角度来看，我们最近的研究主要集中在用废旧聚合材料和废润滑油（ULO）对沥青进行流变和化学改性，从而实现两个重要目标，即获得具有抗伊拉克气候流变特性的沥青以及消除固体和液体环境污染物。使用扫描电子显微镜（SEM）对设计的贴片的微观结构和形态进行表征以表明相组成。
