|Abstract:||This study evaluated the pavement performances of polyethylene (PE) modified asphalt mixture (PEHMA) containing reclaimed asphalt pavement (RAP). A series of RAP (80-100 wt%) were added into PEHMA to replace natural aggregate for the manufacture of RAP–PEHMA. Marshall design method was employed to prepare related specimens to determine the permanent deformation, water sensitivity, low temperature crack resistance and fatigue properties. The results show that RAP–PEHMA performs better rutting resistance than the PEHMA (control mixture), which means that the RAP could improve the high temperature performance of PEHMA. Conversely, RAP–PEHMA made with PE and RAP displays worse water stability, low temperature stability, fatigue performance than that of PEHMA, but all of them could satisfy the current mixture requirements in China.|
