In order to study the influence of different forming methods on the mechanical properties of cold recycled emulsified asphalt mixture, Marshall specimens and cylinder specimens were prepared and tested. The effects of vertical vibration method and traditional method on mechanical properties of cold recycled mixtures were studied, and the fatigue equation was established by Weibull distribution. The results show that the optimum moisture content, emulsified asphalt content and maximum dry density of the vertical vibration method are reduced by 10%, 10% and 1.021 times, respectively, compared with those of the traditional method. Compared with the Marshall specimen, the Marshall stability, splitting strength and freeze-thaw splitting strength of the vertical vibration cylinder specimen are increased by at least 40%, 32% and 57% respectively. The results show that the vertical vibration method is superior to the Marshall method in fatigue resistance and sensitivity to stress change under high stress. The intercept a of fatigue equation of the specimens formed by the vertical vibration method is larger than that of the Marshall method, while the slope B is just the opposite.
