Abstract:
In order to analyze the impact rules of molding way,gradation and binder dose on fatigue properties of cement stabilized macadam, the orthogonal test method was used to test the fatigue performance of cement stabilized macadam under different conditions. Weibull distribution function was used to analyze the fatigue test results and the sensitivity sequence of fatigue performance influencing factors of cement stabilized macadam were determined by the range analysis method. The correlation between the sequence of influencing factors and the fatigue performance was analyzed by the theory of material microscopic composition. The results shows that the sensitivity sequence of various factors on the fatigue life is molding way, amount of cement and gradation. The anti-fatigue performance of cement stabilized macadam can be improved by using vibration molding design method, increasing the amount of cement binder appropriately and selecting suspension dense gradation. 10 tabs, 3 figs, 10 refs.
