本研究的目的是成功地利用回收的计算机塑料中的电子垃圾(电子垃圾)对沥青结合料进行改性，以改善沥青结合料的性能。电子废粉与沥青结合料的掺入量分别为2.5%、5%和15%。对改性沥青结合料和未改性沥青结合料样品进行了旋转粘度、动态剪切流变仪测试和弯曲梁流变仪测试。电子废粉的加入增加了粘结剂的粘度和混合及混合温度，并降低了车辙敏感性，而较低比例的电子废粉改性沥青结合料在指定的低温等级下与对照沥青结合料的m值相似。DOI：10.1061/(ASCE)MT.1943-5533.0000504。(C)2012年美国土木工程师学会。
This study was intended to successfully implement asphalt binders modified with electronic waste (e-waste) from recycled computer plastics to improve asphalt binder performance versus conventional asphalt binders. The e-waste powder percentages blended with asphalt binders were 2.5, 5, and 15%, respectively. Rotational viscosity, dynamic shear rheometer testing, and bending beam rheometer testing was conducted upon modified and virgin asphalt binder samples. The addition of e-waste powders increased binder viscosity and blending and mixing temperatures and decreased rutting susceptibility versus virgin asphalt binders, and lower percentages of e-waste powders modified asphalt binders resulted in similar m-values at the specified low temperature grade of the control asphalt binder.
