Abstract

The recycled packaging waste EPS and PE were adopted to modify the asphalt and the two kinds of modified asphalts were researched comparatively. The results show that the high-temperature property and anti-shearing deformation capacity of the waste PE modified asphalt were both better than that of EPS. However, the ductility of the waste EPS modified asphalt got a larger improvement than the one made by PE. The main reasons of these differences are the aromatic composition, non-polarity of EPS and the large range of viscoelasticity, big molecular and good elongation of PE in modified asphalt system.
