| 摘 要： | 基于数字图像处理技术，对沥青混合料均匀性指标的部分影响因素——成型方法与集料类型，展开定量研究．研究结果表明：不同的成型方法，对沥青混合料均匀性指标的影响会有所不同，室内研究中，成型方法对沥青混合料均匀性指标的影响大小依次为：轮碾成型，马歇尔击实，旋转压实；不同类型的集料，对沥青混合料均匀性指标有着不同程度的影响，相同的集料类型，不同的集料产地，在其他条件都基本相同的情况下，其对应的沥青混合料均匀性指标基本相同．

| Abstract: | Based on digital image processing,some influence factors of the index of asphalt mixture homogeneity such as experimental method and aggregate type are quantitatively investigated.The research results reveal that different experimental methods influence the index of asphalt mixture homogeneity to different extents,and at laboratory,the effects of experimental methods on the index can be rated as following: rolling wheel compaction,impact compaction(The Marshall) and gyratory compaction.Different aggregate types also influence the index of asphalt mixture homogeneity to different extents.When the other conditions are indentical,the same aggregate type of different sources influences the index to a nearly equal extent. |
