不同纤维掺量沥青混合料的马歇尔试验

Marshall Experiment of Bituminous Mixture of Different Fiber Proportions

使用马歇尔试验方法确定AC-13普通沥青混合料的最佳油石比，又通过马歇尔试验对不同纤维掺量的沥青混合料进行对比分析，比较在不同纤维掺量下沥青混合料稳定度、密度、空隙率、流值的变化情况，最终确定了不同纤维掺量沥青混合料的最佳油石比。

Marshall Experiment method is used to determine the optimum asphalt-aggregate ratio of the AC-13 common bituminous mixture. The change of degrees of stability, density, void ratio, and low value in different fiber proportions of bituminous mixture are analyzed and compared by the Marshall Experiment. Then it concluded the optimum asphalt-aggregate ratio of different fiber proportions of bituminous mixture.
