摘　　要：为了研究纤维掺量和种类对沥青胶浆粘度的影响,选择木质素纤维、聚酯纤维、矿物纤维三种纤维与沥青拌和制作沥青胶浆试件,纤维掺量分别为0%、0.1%、0.3%、0.5%和1%,采用Brookfield旋转粘度计进行不同温度下的粘度试验,探讨了纤维沥青胶浆粘度的影响因素,并采用Einstein混合率理论对纤维的增粘效应进行了分析。To study the effect of the quantity and variety of fiber mixed on the viscosity of asphalt mortar,the three fibers of lignin fiber,polyester fiber and mineral fiber are selected to mix with asphalt to make the test specimen of asphalt mortar,with the respective quantity of fiber applied of 0%,0. 1%,0. 3%,0. 5% and 1%.Besides,the viscosity test at different temperatures is made with Brookfield rotary viscometer,with which it is discussed about the factors may influence the viscosity of fiber asphalt mortar. Moreover,an analysis is provided on the viscosity promotion effect on fiber with the theory of Einstein mixing ratio.
