| 摘要: |
| 为了分析矿料接触面的细观强度特性,研究剪切效应下沥青与矿料表面粘附强度及沥青结合料自身粘结强度的定量测试技术．根据矿料接触面破坏方式及沥青与矿料表面剪切粘附强度、粘附失效区面积、沥青剪切粘结强度、粘结失效区面积与剪切破坏荷载的对应关系,确定沥青剪切粘结强度和沥青与矿料表面的剪切粘附强度,实现矿料接触面上粘附与粘结强度的定量测试．测试结果表明:沥青与矿料表面剪切粘附强度受试验温度及矿料接触面上油膜厚度影响较大,同时沥青品质也对其大小产生影响;沥青结合料剪切粘结强度与试验温度及沥青品质有较大相关性． |

| Abstract: |
| To analyze the mesoscopic strength characters of aggregate contact surface, the quantitative testing technology of adhesion strength between bitumen and aggregates and the cohesion strength of bitumen binder itself under shear load were researched. According to the failure forms and the corresponding relationship of shear adhesion strength between aggregates and bitumen, adhesion failure area, shear cohesion strength of bitumen binder, cohesion failure area and shear failure load, the shear cohesion strength and shear adhesion strength can be determined, and the quantitative test of adhesion and cohesion strength of mineral aggregate contact surface can be realized. The test results show that the experimental temperature and oil film thickness of mineral aggregate contact surface have a big influence on shear adhesion strength, besides, the quality of bitumen also has an effect on it. The shear adhesion strength of bitumen binder has strong correlation with experimental temperature and the quality of bitumen. |
