| 摘 要： | 以参数B为表征沥青-集料交互作用能力的评价指标,利用动态剪切流变仪对2种沥青与4种集料在不同粉胶比条件下相互作用后的沥青胶浆进行了流变性能研究,分析了沥青-集料交互作用能力随温度及荷载频率的变化规律,确定了评价沥青-集料交互作用能力的外部条件。结果表明：随着温度的升高,沥青-集料交互作用能力的增大幅度呈现先小后大的特点;高温和低温下,加载频率对沥青-集料交互作用能力的影响恰好相反。 |

| Abstract: | The parameter B was used as the evaluation index for the asphalt-aggregate interaction ability.The rheological properties of asphalt mastics using two kinds of asphalts and four kinds of aggregates under different filler-asphalt ratios were measured with a dynamic shear rheometer.The interaction ability of asphalt and aggregate changing with temperature and loading frequency was analyzed,and the external conditions for evaluation of asphalt-aggregate interaction ability were determined.The results show that with the temperature increasing,the interaction ability of asphalt and aggregate is small at first and large at last,while the influence of loading frequency on interaction ability of asphalt and aggregate is opposite under both high temperature and low temperature. |
