Research on Fatigue Performance of Modified Asphalt Mixture in Intermediate Course of pavement

摘要

Beam bending fatigue test was done by MTS810 using stress control mode, the double logarithm fatigue equations and Weibull fatigue equations of three types of modified asphalt mixtures for intermediate course under different design method are gained. Good performance of the modified asphalt mix design programs are choose to use in the Northeast region to explore the modified asphalt mix design method for the use of intermediate course through a comparative study of 3 types of modified asphalt mixture fatigue performance.
