| 摘 要： | 沥青混合料的高温稳定性是影响沥青路面路用性能的一个主要因素，在实际工程中往往由于高温稳定性不好而导致路面发生不同程度的病害。基于灰熵分析法，讨论了马歇尔特征值对沥青混合料的影响程度，研究认为马歇尔稳定度、VMA和油石比对于沥青混合料的影响显著，VFA和VV次之，毛体积密度最小，这为沥青混合料的设计提供科学的依据。

| Abstract: | The high temperature stability of asphalt mixture is a major factor to affect the performance of asphalt pavement. In practical engineering, varying degrees of surface defects often happen because of poor high temperature stability. Based on gray entropy analysis method, the influence of Marshall eigenvalue on the asphalt mixture is studied to provide a scientific basis for the design of asphalt mixture. |
