Effect of Rejuvenator on Porous Asphalt Mixtures Containing Reclaimed Asphalt Pavement (RAP) Material

Abstract:

Based on the background of continuously increasing requirements on the performance of recycle pavement materials, the effect of rejuvenator with different content (3%, 6%, 9% and 12%) and different type on recycled porous asphalt mixture was studied in this paper. The results shown that comparing with the ordinary rejuvenator which softening the aged binder effectively, the modified functional rejuvenator can also enhance the temperature stability and deformation resistance capacity of aged asphalt. In addition, the recycled porous asphalt mixture with modified functional rejuvenator has more excellent high temperature stability, water stability and fatigue performance. The result has great significance for the development of pavement recycling technology.
