Abstract:High temperature performance of three high performance modified asphalts(A, B and C) and SBS modified asphalt were characterized by multiple stress creep recovery(MSCR) test. Their non recoverable creep compliance(Jnr), percent recovery(R) and the corresponding stress sensitivity indexes were analyzed. The high temperature performance of asphalt mixtures fabricated by those four asphalt binders were evaluated through wheel tracking tests and dynamic creep tests. Ultimately, regression analyses were carried out between high temperature performance parameters of asphalt binder and asphalt mixture. The results show that the Jnr of A and C is comparatively smaller and percent recovery is bigger than SBS modified asphalt and B under different stresses. In addition, the stress sensitivity of A and C is lower than that of B and SBS modified asphalt. Furthermore, the high temperature rutting resistance of A mixture and C mixture is superior to the other two asphalt mixtures. Comparing with tracking tests, the dynamic creep tests show better correlation with Jnr and R. It is more reasonable to use Jnr and R of asphalt binders at 32, 64and 128kPa to evaluate the high temperature performance of modified asphalt mixtures. The application of A and C could improve the high temperature stability performance of steel bridge deck pavement dramatically.
