| 摘要: |
| 采用AC 20级配，对软硬复合沥青温拌混合料的各项性能指标进行了研究，并与相同级配、相同配合比的热拌70#沥青混合料进行了对比分析.结果表明：软硬复合沥青温拌混合料在高温稳定性方面与相同级配的热拌沥青混合料相当，水稳定性稍逊，低温抗裂性略优，而疲劳性能则明显占优. |

| Abstract: |
| By use of AC 20 gradation, the performance indicators of warm mixture of soft and rock asphalt compound were discussed and compared to the same level of the hot mix asphalt（HMA）. Test and analysis result indicated that warm mixture of soft and rock asphalt compound is equivalent to the same grading of hot asphalt mixture at high temperature stability, however, its stability in water is worse. Nevertheless, its low temperature cracking resistance is slightly better, and fatigue performance is significantly outstanding. |
