废弃塑料和废弃胎胶的增值综合回收及其在路面工程中的可持续性实践
Sustainable Practice in Pavement Engineering through Value-Added Collective Recycling of Waste Plastic and Waste Tyre Rubber
废弃聚对苯二甲酸乙二醇酯（PET）饮料瓶等废弃塑料和废弃橡胶轮胎为主要的城市固体废弃物，如不进行合理回收，可能会引发各种环境问题。本研究对这两种废弃物经综合处理后用作沥青路面性能增强改性剂的可行性进行了分析。通过采用三乙烯四胺（TETA）和乙醇胺（EA）对废弃PET进行处理，分析废弃PET经处理获得添加剂的回收机理，同时表征这两种添加剂在改性橡胶沥青过程中的表现。鉴于此，本文采用红外光谱和热分析法对PET添加剂（PET-TETA和PET-EA）进行了研究，进而通过红外光谱、黏度、动态剪切流变和多次应力蠕变恢复等试验对这两种PET添加剂改性的橡胶沥青进行了分析。结果表明：通过化学处理后，废弃PET可被增值回收为功能性添加剂，以提高橡胶沥青的整体性能。本研究所开发的回收方法不仅有助于缓解废弃PET塑料和废弃轮胎的填埋问题，而且可将这些废弃物转变为耐久性路面建设的高附加值新材料。
Waste plastics, such as waste polyethylene terephthalate (PET) beverage bottles and waste rubber tyres are major municipal solid wastes, which may lead to various environmental problems if they are not appropriately recycled. In this study, the feasibility of collectively recycling the two types of waste into performance-increasing modifiers for asphalt pavements was analyzed. This study aimed to investigate the recycling mechanisms of waste PET-derived additives under the treatment of two amines, triethylenetetramine (TETA) and ethanolamine (EA), and characterize the performances of these additives in modifying rubberized bitumen, a bitumen modified by waste tyre rubber. To this end, infrared spectroscopy and thermal analyses were carried out on the two PET-derived additives (PET–TETA and PET– EA). In addition, infrared spectroscopy, viscosity, dynamic shear rheology, and multiple stress creep recovery tests were performed on the rubberized bitumen samples modified by the two PET-derived additives. We concluded that waste PET can be chemically upcycled into functional additives, which can increase the overall performance of the rubberized bitumen. The recycling method developed in this study not only helps alleviate the landfilling problems of both waste PET plastic and scrap tyres, but also turns these wastes into value-added new materials for building durable pavements.
