虽然纤维沥青混凝土路面在我国的部分地区得到了初步应用,但对大部分施工单位而言,并不了解这种新型材料和普通沥青混凝土路面在哪些方面存在不同,因此妨碍了其进一步推广应用。从设计与施工控制角度着手,通过对采用不同类型纤维和纤维用量的沥青混凝土进行马歇尔试验,得到了加入纤维后沥青混凝土马歇尔指标的变化规律,为施工时选择纤维和确定纤维用量提供了依据,增强了纤维沥青混凝土路面推广应用的可操作性。
Although the fiber asphalt concrete pavement has been initially applied in some areas of our country, most construction units do not understand the difference between the new material and ordinary asphalt concrete pavement, which hinders further application. From the perspective of design and construction control, the Marshall test of asphalt concrete with different types of fiber and fiber was used to get the change rule of Marshall index of asphalt concrete after adding fiber, which provided the basis for selecting fiber and determining the amount of fiber during construction. Enhance the feasibility of popularization and application of fiber asphalt concrete pavement.
