纤维沥青胶浆高低温性能研究
Study of high and low temperature performance of fiber-asphalt mortar
摘要
Abstract
The softening point, cone sink experiment, dynamic shear rheometer (DSR) and bending beam rheometer (BBR) were conducted to evaluate the effects of the ratio of filler to asphalt ( ROFTA) , fiber content ( FC) and fiber type on the high and low temperature properties of fiber-asphalt mortar. The results show that the fiber increases the high temperature stability of asphalt mortar greatly, in which the lignin fiber shows better improvement than the mineral fiber. The increase of ROFTA and FC improves the high temperature performance of asphalt mortar significantly. However, they have some negative effects on low temperature performance. Also, fiber-asphalt mortar presented significant temperature susceptibility, increasing temperature will induce the improvement of low temperature cracking. When the ROFTA decreases 0. 2 and lignin content increases 1%, the rheological property of the fiber-asphalt mortar is approximately equal to that of pure asphalt mortar.关键词
