Abstract: In this paper, waste packaging polyethylene (WPE)/organic montmorillonite (OMMT)
nanocomposites were prepared and used as an asphalt-modifying agent. The structure and
morphology of the nanocomposites and the effects of OMMT on the thermal properties of WPE
were investigated. The influence of the microcosmic effects and physical properties of the
composite agents on the base asphalt were also studied. The results show that the WPE/OMMT
asphalt-modifying agents are exfoliated nanocomposites. When compared with WPE, the melting
range of the composites decreases and the thermal stability is improved. In addition, the
composite agents not only promote good dispersion of WPE in asphalt, but also improve the low
temperature properties of WPE-modified asphalt without adversely affecting its excellent high
temperature properties. Therefore, from an environmental and economic standpoint, it is a novel
and significant attempt at dealing with waste plastics packaging. © 2013 Elsevier Ltd. All rights
