Abstract: The cold recycling technology stabilized with emulsified asphalt is mostly used in the base layer of pavement. Applying it on the surface course is beneficial to the increase of utilization rate of waste material. But at the same time, attention should be paid to the anti-reflective crack performance of the mixture. This paper used the OT test to discuss the influence of different material components on the crack resistance of cold mixture with emulsified asphalt, as well as the design index and corresponding criteria. The results show that the load loss rate after 1 200 load times is qualified as the design index for cold mixture with emulsified asphalt used in surface course. Various factors, including types of aggregate grading, cement and base asphalt, dosage of RAP and cement all have significant influences on the load loss rate. To improve the anti-reflective crack performance of emulsified cold mixture for surface course, the dosage of RAP should not exceed 70%, and the cement should not exceed 1.5%. The PO42.5 cement, the emulsified asphalt made with 70# base asphalt and coarse aggregate gradation are preferential in the raw material selection. It is recommended to supplement the evaluation on anti-reflective crack performance with OT test in the mix design of emulsified cold mixture for surface course, and the load loss rate is required to be less than 80%.
