    摘要:

    应用小型加速加载设备MMLS3,对45℃时水荷耦合作用下的沥青混合料永久变形规律进行了研究.通过与单独荷载作用下沥青混合料永久变形的比较和分析发现: 沥青混合料在水荷耦合作用下的永久变形整体高于单独荷载作用,水对永久变形的影响突显于压密变形阶段;水荷耦合作用下沥青混合料的蠕变速率较单独荷载作用时大,封闭在沥青混合料空隙内部的水一定程度上有助于抗变形能力;水荷耦合作用与单独荷载作用时沥青混合料的变形比与荷载运行次数呈幂函数,且随荷载运行次数的增大而降低.

    Abstract:

    Applying the MMLS3 system, permanent deformation of asphalt mixture was studied at 45℃ under moisture loading action. Compared with the rutting behavior under dry condition, the results are drawn that, the rutting depth is higher under water condition than dry condition, the effects of water is mostly shown in the initial compression phase. The creep slope of specimen under immersion increases, compared to the specimen under dry condition. The deformation ratio between moisture and dry condition follows the power function relationship with the loading number, and decreases with loading number increasing.
