| 摘 要： | 通过新型的试验方法对比室内制作的SMA-13和在不同压实温度条件下成型的掺入3%的Sasobit温拌剂下的SMA-13马歇尔试件的一系列体积指标,确定掺入Sasobit温拌剂下SMA-13的室内最佳压实温度范围,进而确定现场摊铺温度为140℃左右;通过比较两种不同混合料的高温性能、低温性能以及水稳性能,试验结表明：掺入3%的Sasobit温拌剂的SMA-13混合料高温性能优于普通的SMA-13混合料,低温与水稳性能略低于普通的SMA-13混合料。

| Abstract: | By comparing Marshall specimen of indoor-produced SMA-13 mixture and the one mixed with 3% Sasobit, this study determines a series of volume indices and the mixing and pavement compaction temperature with the added Sasobit. The comparison results of high temperature properties and water stability for two different mixtures show that the performance of SMA-13 mixture with 3% Sasobit at high temperature is superior to the common SMA-13 mixture, while its low temperature properties and water stability are slightly lower. |
