Study on the Freeze-to-Crack Test of Asphalt Modified by Waste-PE in Packing

Abstract:

The purposes of this study are to modify asphalt by retrieved waste-PE in packing (WPP) and to investigate the low temperature properties of the modified asphalt. The traditional testing methods such as low temperature ductility, low temperature penetration degree, penetration or Fraass breaking point think that PE can not improve the low temperature properties of asphalt effectively, while this study adopts a new method to test the low temperature properties of WPP modified asphalt through the freeze-to-crack test. The result indicated that, after the modification, the low temperature properties of asphalt are improved, which coincides with the fact. And the improvement of the low temperature properties can be explained by the function of Shear yield and crack pinning.
