Paper Title:
Study on Pavement Performance of Reclaimed Asphalt Mixture
  Abstract

In order to improve the pavement performance of reclaimed asphalt mixture, using Marshall test, rutting test, splitting test and long-term aging test, taking stability, dynamic stability, fatigue strength, stiffness modulus, and freeze-thaw splitting tension strength as the target, the influence law of old asphalt mixture content and regenerant content on pavement performance of reclaimed asphalt mixture is systematically studied. The results show that: the proportion of old asphalt mixture has no influence on high temperature performance of reclaimed asphalt mixture. With the proportion of old mixture increases, the optimum asphalt-aggregate ratio, low temperature performance, water stability, and anti-aging property of reclaimed asphalt mixture decrease. Addition of regenerant improves the low temperature performance of reclaimed asphalt mixture, and reduces the strength and high temperature stability of reclaimed asphalt mixture. Research results have great guiding significance for old asphalt mixture content selection, regenerant content selection and improving pavement performance of reclaimed asphalt mixture.
