In order to investigate the influence of different moulding methods on the mechanical properties of cold recycled emulsified asphalt mixture, the effects of vertical vibration method and traditional method on the mechanical properties of cold recycled asphalt mixture were studied by preparing Marshall specimens and cylinder specimens, and the fatigue equation was established by Weibull distribution. The results show that by the vertical vibration method, the optimal moisture content and optimal emulsified asphalt content of the mixture are reduced by 10% respectively, and the maximmum dry density of the mixtare are increased 1.021 times, compared with the mixture by the traditional method. Compared with Marshall Specimens, the Marshall stability M_S, 25 ℃splitting strength and freeze-thaw splitting strength of vertical vibration cylinder specimens increase by 40%, 32% and 57% respectively. Through the intercept a and slope b of fatigue equation, it can be seen that the fatigue resistance and sensitivity of vertical vibration specimens to stress change under high stress are better than those of Marshall method specimens, that is, the value of a in the vertical vibration method is greater than that of Marshall method, and the value of b in the vertical vibration method is less than that of Marshall method.
