Abstract: Cold mix asphalt mixture with solvent-based liquid asphalt has good application prospects in winter pavement maintenance. This paper evaluated the performance of cold mix asphalt mixtures in the lab and field. The initial strength, formed strength, indirect tensile strength and its evolution law were researched through lab tests. The results show that the Marshall stability can reach a high level after fully curing. The curing temperature significantly influences the indirect strength than the curing time. In the field, the patches with different gradations were installed and investigated. The vertical deformation in the different periods was recorded and analyzed. The results show that the mixtures with AC gradation perform well in the lab but disappointing in the field, and the mixtures with LB gradation are more suitable for pothole repair in winter. The inconsistency between lab and field is mainly due to the strength formation mechanism of liquid asphalt mixture and the uneven curing in the field. The uniaxial penetration test was introduced to explore the influence of uneven curing on the strength of the two kinds of mixtures. The results show that open cured mixtures have greater penetration strength. The curing condition indeed influences the strength formation process.
