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。
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.
通过大量路用性能试验，得到AC - 16密级配沥青混合料集料的体积分形维数与路用性能指标之间的相关变化规律。
The correlations between road performance and the fractal dimension of aggregate volume of AC-16 are obtained from road tests.
