| 摘 要： | 通过水煮法、静态水浸法、光电比色法和净吸附法来研究不同类型沥青和集料之间的粘附性，用残留马歇尔试验和冻融劈裂实验研究由不同类型沥青和集料组成的沥青混合料的水稳定性，同时分析了各种不同方法之间的相关性。结果表明，不同性质集料对沥青混合料的水稳定性影响显著，但不能忽视沥青对混合料水稳定性的作用，残留马歇尔试验和净吸附法试验与冻融劈裂实验有着很好的线性相关关系，对于沥青与集料之间粘附性可采用净吸附法试验来评价。对于沥青混合料的水敏感性可采用残留马歇尔试验和冻融劈裂实验来评价。 |
| 关 键 词： | 沥青混合料 水敏感性 冻融劈裂实验 净吸附法 |

| Abstract: | The paper studies adhesion between asphalt and aggregate through boiling method, immersion water method, electrophotometer method and net adsorption method, and studies moisture stability of asphalt mixture through retained Marshall stability test and freezing and thawing split test, and then the paper analyzes correlation of different test methods. The results show that there is significant effect of different aggregates on moisture stability of asphalt mixture, but it can not ignore effect of asphalt on moisture stability. There is better line type correlation between freeze split test and retained Marshall stability, net adsorption test, the net adsorption test can be evaluated to adhesion between asphalt and aggregate, the retained Marshall stability test and freezing and thawing split test can be evaluated to moisture stability of asphalt mixture. |
| Keywords: | asphalt mixture moisture susceptibility freezing and thawing split test |
