Abstract The dynamic creep test and rutting test of matrix asphalt mixture and modified asphalt mixture were carried out, and the sensitivity of creep parameters of hydrophobic nano-silica modified asphalt mixture to dynamic stability was deeply analyzed.The results show that the dynamic stability of the asphalt mixture can be effectively improved by the silane silica, and the rutting test results are well correlated with the established relationship model. The sensitivity of dynamic creep permanent deformation parameters to dynamic stability is analyzed. It is concluded that the viscosity coefficient η₁ is positively correlated with the change of dynamic stability (DS), and the viscosity coefficient η₁ is the most sensitive to dynamic stability (DS). The sensitivity of viscosity coefficient to dynamic stability can be effectively improved by adding silane silica.

Key words： silica dynamic stability sensitivity dynamic creep test rutting test
