Abstract:
The macro-texture of asphalt pavement greatly affects the traffic safety of driving. In this study, the 3D laser scanning data, which is captured from the pavements, is used for reverse modeling. FE software ANSYS is used to analyze the contact stress distribution of pavement macro-texture and tire. The results show that the macro texture will be affected by fatigue failure considering the size effect of coarse aggregate. The fatigue life distribution of pavements is analyzed using the fatigue analysis software FE-SAFE which is based on linear cumulative damage theory. The developing tendency of texture depth with respect to the number of loading times is obtained by analyzing the results of fatigue life. Compared with the results of accelerated loading test shows that the factor of fatigue failure has remarkably affected the macro texture under low loading times. This effect is gradually decreased with the increasing of cyclic loading times. © 2017 Chinese Society of Pavement Engineering
