| 摘 要： | 介绍了改性沥青混合料中沥青膜厚的计算方法，分析了沥青膜厚的影响因素，着重研究了沥青膜厚与沥青混合料性能的关系，通过对稳定度，动稳定度分析表明，稳定度与沥青膜厚曲线均呈驼峰形状，具有明显的峰值，沥青膜厚与动稳定度也呈驼峰关系，并与稳定度峰值存在对应关系，两者在同一膜厚达到最大值。

| Abstract: | Asphalt mixture pavement is extensively used in high grade high way in the word. It is very important to ensure high performanceof asphalt mixture with adequate thick asphalt film. The paper was to introducethe calculating method of asphalt film thickness and analyze the affecting factors. Experiential result showed that the stable and asphalt film thickness curve was hump shape. Dynamical stable was had a max one with the increase of asphalt film thickness. |
