摘要：

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.
