Cold patch asphalt is more preferable in pavement construction compared to hot mix asphalt from the perspective of environmental conservation. However, the cold patch asphalt mixture is prone to moisture damage for production at lower temperatures and the presence of a diluent. The objective of this paper is to evaluate the moisture induce damage potential of cold patch asphalt mixture based on surface free energy theory. Three kinds of cold patch asphalts were synthesized by base asphalt, abietic resin, diesel, and anti-stripping agent, while the aggregates consisted of limestone and basalt. The surface free energy components of cold patch asphalt and aggregates were measured using the high-precision automatic Tensiometer System and Gravimetric Sorption Analyzer, respectively. The analytical computation to assess cohesive bond energy, wettability, adhesion bond energy, and energy ratio was obtained after surface free energy calculations. The results showed that the mixture of additives decreased the surface free energy of cold patch asphalt. Moreover, diesel can increase the surface free energy of pure asphalt. However, the abietic resin and anti-stripping agent have an adverse effect. Therefore, it can be concluded that the cold patch asphalt synthesized in this study has better resistance to water damage ability than base asphalt. More cold patch asphalt and aggregates are strongly suggested to validate the findings of this research.

从环境保护的角度来看，冷补沥青比热拌沥青更适用于路面施工。然而，冷补沥青混合料易于在较低温度和稀释剂存在下生产时受到水分损坏。本文的目的是基于表面自由能理论评估冷补沥青混合料的水分诱导损伤潜力。以基础沥青、松香树脂、柴油和抗剥落剂为原料合成了三种冷补沥青，骨料为石灰石和玄武岩。分别使用高精度自动张力计系统和重力吸附分析仪测量冷补沥青和集料的表面自由能分量。评估内聚键能、润湿性、表面自由能计算后得到粘附键能和能量比。结果表明，添加剂的混合降低了冷补沥青的表面自由能。而且，柴油可以增加纯沥青的表面自由能。然而，松香树脂和抗剥离剂有不利影响。因此，可以得出结论，本研究合成的冷补沥青比基础沥青具有更好的抗水损害能力。强烈建议使用更多冷补沥青和集料来验证本研究的结果。柴油可以增加纯沥青的表面自由能。然而，松香树脂和抗剥离剂有不利影响。因此，可以得出结论，本研究合成的冷补沥青比基础沥青具有更好的抗水损害能力。强烈建议使用更多冷补沥青和集料来验证本研究的结果。柴油可以增加纯沥青的表面自由能。然而，松香树脂和抗剥离剂有不利影响。因此，可以得出结论，本研究合成的冷补沥青比基础沥青具有更好的抗水损害能力。强烈建议使用更多冷补沥青和集料来验证本研究的结果。
