From this analysis, it appears that the interaction of asphalt content and finegradation has the most significant effect on the percentage of air voids.
从这分析，看起来，沥青内容和美好的渐进性的互作用有最重大的作用在空气空隙的百分比。

The results show that best permanent deformation resistance can be got when continuous dense gradation, which has even arrangement of coarse and fine aggregate is adopted.
结果表明，采用粗细集料搭配均匀的连续密级配和适中的沥青用量可以获得最佳的抗永久变形能力。
