Cylindrical specimens were prepared by vertical vibration molding method. The effects of mineral powder, machine made sand and 95190mm coarse aggregate content on the strength of cold recycled asphalt mixture(CRM) were studied. The results show that the mineral powder content(by mass) is less than 5%, with the increase of the mineral powder content, CRM strength increases, but the increase rate gradually lowers. When mineral powder content is greater than 3%, compared to emulsified asphalt cold recycled mixture without new aggregate, the mechanical strength increases at least 5%. Adding machine made sand, CRM strength increases first, then decreases. When the sand content is 20%, the Marshall stability of mixture, dry wet splitting strength and freeze thaw splitting strength reach the peak, and the mechanical strength can be increased by more than 17%. With the 95190mm coarse aggregate content increasing, the dry wet splitting strength of mixture increases first and then decreases. When the 95190mm of coarse aggregate content is 20%, CRM strength increases by at least 19%. Therefore, considering the material cost, it is suggested that the content of mineral powder in CRM is 3%, the content of machine made sand is 20%, and the content of 95190mm coarse aggregate is 20%.
