Asphalt Modified with Nonmetals Separated from Pulverized Waste Printed Circuit Boards

Guo, Jiuyong, Guo, Jie, Wang, Shifeng, Xu, Zhenming·2009·Environmental Science & Technology

Abstract

Nonmetals separated from pulverized waste printed circuit boards (PCBs) were reused as a new modifier to improve the performance of asphalt. The classical and rheological properties of unmodified asphalt and non-metal-modified asphalt (NMA) were determined. Specifically, the influence of nonmetals content and particle size on these properties has been studied. When the nonmetals content was 25 wt% and the particle size group was 0.07-0.09 mm, the NMA had a viscosity of 1225 cP at 135 degrees C, a penetration of 53.7 dmm at 15 degrees C, a ring and ball softening point of 54 degrees C, a ductility of 43.5 cm at 15 degrees C, a G*/sin delta of 3995.27 Pa at 60 degrees C, and an upper limit temperature (G*/sin delta = 1 kPa) of 69.4 degrees C, all of which showed that the high temperature performance of asphalt was improved significantly. Therefore, this study gives a fundamental understanding of NMA and represents a novel attempt to deal with the fast increasing quantities of nonmetals from waste PCBs, which is significant from an environmental and economic standpoint.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
