Paper Title:
Performance Evaluation of BRA Modified Asphalt Based on Analysis of Rheological Property
  Abstract

With the experiments of dynamic shear rheometer(DSR), bending beam rheometer(BBR) and Brookfield rotary viscometer, the rheological performance of Buton Rock Asphalt (BRA) modified asphalt is tested and analyzed. The results indicate that the high temperature PG grades, the anti-rutting indicator and the viscosity are all increased, the high temperature stability is enhanced greatly and the temperature sensitivity is reduced after the addition of BRA modifier. Furthermore, the change rate increases with the increase of the additive; the creep stiffness modulus increases and low-temperature performance decreases at a low temperature, so the dosage of BRA should be appropriately considered in the process of application.
