| Abstract: | In this paper, fatigue performances of different types of asphalt mixtures and different preventive measures of reflective cracking are studied by simulating tests. The load and the temperature stress in the semi-rigid pavement are analyzed with finite element method. According to the result above, the mechanisms of the reflective cracking and its preventive measures are studied. |
