| 摘 要： | 半刚性基层沥青路面早期破坏严重,沥青稳定碎石基层以其优良的性能逐渐得到广泛的应用。只有采取科学的方法才能设计出性能优良的沥青稳定碎石基层。以ATB-30为例,采用三种不同的设计方法确定混合料的级配和最佳沥青用量,并根据基层作用和受力特点,通过抗竖向变形和耐疲劳性能对比及其机理分析,选择出适合于沥青稳定碎石基层的设计方法,对工程实践具有极大的参考价值。

| Abstract: | The premature failure of semi-rigid base asphalt pavement is serious,therefore asphalt treated base has got widespread application for its excellent performance.Only through good design method can the excellent asphalt treated base be designed.Taking ATB-30 for example,three different design method are used to determine the mixture gradation and the optimum asphalt content.Meanwhile according to the base action and bearing characteristics,anti-vertical deformation and anti-fatigue are compared and analyzed to select the design method suitable for asphalt treated base.It can provide reference for engineering practice. |
