The Properties of Modified Asphalt Binders Blended with Electronic Waste Powders

Civil Engineering CE 5990 Graduate Seminar

Thursday, January 26
Time: 4–5 p.m.
Location: Dow 642
Public is welcome

Presenter: Baron Colbert, Ph.D. candidate, Department of Civil and Environmental Engineering (Adviser: Dr. Zhaping You)

Abstract: This study was intended to successfully implement asphalt binders modified with electronic waste (e-waste) from recycled computer plastics in order 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, blending and mixing temperatures, 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.
