纤维沥青混合料马歇尔试验

Marshall index of fibers-reinforced asphalt mixture

近年来 ,纤维沥青路面得到了广泛应用 ,但在设计与施工中却存在许多问题 ,对其推广应用不便。为了便于设计与施工控制 ,通过对不同纤维类型、纤维长度、细度及纤维用量的沥青混合料马歇尔试验研究 ,分析了纤维对沥青混合料马歇尔试验结果影响的原因 ,从而得到了纤维沥青混合料马歇尔指标的变化规律 ,为纤维沥青混合料设计与施工提供了依据 ,为大面积使用该路面结构提供了便利条件。

In recent years, fibers-reinforced asphalt mixture has been widely used in pavement construction, but there are many problems to be solved for its design. Marshall test was carried out to study the influnce of fiber's styles, length and fineness on the pavement performance, so as to reveal the changing law of Marshall index.
