摘要：

To provide theoretical and data support for the fatigue performance test and life prediction of rejuvenated asphalt mixture, and supply parameter support for the design of rejuvenated asphalt pavement, dynamic shear rheometer (DSR) was used to conduct repeated shear tests on original asphalt, wood tar-based rejuvenated asphalt and RA-102 rejuvenated asphalt to evaluate the rationality of three parameters are defined as follows: complex modulus parameter (Nf50), dissipated energy ratio parameter (NP20), ratio of dissipated energy change parameter (Nfm) for evaluating the fatigue performance of ...
