| 摘 要： | 采用改进的ACl3＋AC20双层组合式车辙试验方法，对沥青混合料组合式结构高温条件下永久变形规律进行了观测，并同现行单层车辙试验方法下的ACl3、AC20车辙板变形规律进行了比较和分析。结果表明：组合式车辙板的永久变形要小于同等条件下单层板的变形；其动稳定度介于AC20与ACl3两者其间；组合式车辙试验不仅反映了混合料材料特性，而且反映了混合料组合层的结构特性。

| Abstract: | The structural permanent deformation was researched using modified rutting test, which combines both AC13 and AC20 mixture slab, and compared with the normal single AC13, AC20 rutting slab. The results were drawn that, the rutting depth of combined slab is lower than the single slab under the same test condition; however the dynamic stability is between the two single slabs. Combined rutting test can not only show the asphalt mixtures＇ material characteristics, but also the layered mixtures＇ structural characteristics. |
