| 摘 要： | 分析了SMA混合料设计的局限性,对旋转压实方法设计SMA混合料的可行性进行了分析。试验结果表明,合理的压实功选择对于SMA配合比设计有很大影响。SGC可以很好的模拟路面的压实情况,但是照搬美国的标准设计SMA配合比仍不可取,需要适当降低压实次数以符合我国国情,100次较为合理。

| Abstract: | The limitation of the SMA mixture designing methods in china was analyzed,then the Superpave Gyratory Compactor(SGC) method for SMA mixture where designing applicable and feasibility is analyzed,and SGC method is introduced to promote the application in SMA mixture design.It is found that the compaction work determined by the SGC design procedure is remarkably increased compared to that by Marshall design when the number of gyrations is 100.It is recommended that the number of gyrations should be decreased instead of 100 when SGC is used to design SMA mixture in China. |
