| 摘 要： | 马歇尔沥青混合料设计方法考虑了稳定度等力学指标和体积指标,但是用稳定度作为力学指标对工程实际中出现的病害没有很好的针对性。如沥青路面的疲劳破坏,其与沥青混合料的抗拉强度存在很大的联系。通过用沥青混合料的抗拉强度代替稳定度进行下面层沥青混合料的设计,能在源头对沥青路面可能发生的疲劳破坏给予控制。

| Abstract: | The stability and volume are considered as indexes in Marshall asphalt mixture design method,but using stability as the mechanical index can′t target the diseases appearing in engineering.For example,there exist strong links between fatigue disease of asphalt pavement and tensile strength of asphalt mixture.The fatigue damages occurring in asphalt pavement could be controlled in the source through substituting tensile strength for stability in designing lower layer asphalt mixture. |

| Keywords: | asphalt mixture tensile strength optimal asphalt-aggregate ratio |
