Abstract: The present study presents an investigation into the dynamic modulus of asphalt mixture and mix- ing different PR. MODULE of asphalt mixture under different temperature and different loading frequen- cy .The results show that the ｌｏａｄ frequency is constant, the dynamic modulus decreases with the increase of temperature;At a certain temperature, the dynamic modulus increases with the increase of frequency;When frequency and temperature are constant, the dynamic modulus of asphalt mixture is widely increases as amount of PR. The MODULE increases, and there must be a optimum content of the PR. MODULE.
