摘要：

To increase the performance of bituminous mixture with basalt fiber, the influence laws of fiber type, length and proportions were studied, which was on the crack resistance property, shear performance and rheological property of bitumen mastics.Then, based on the relevance research on performance of bitumen mastics and correspon-ding mixtures, micro enhancement mechanism of basalt fiber on bituminous mixture was explored.The results showed that basalt fiber could promote the crack resistance property and rheological property of bitumen mastics effectively, which performed that its ultimate tension was increased by 3.5 times and the rutting factor 1.08 times as much as original bitumen mastics.There were obvious differences between the rheological property of bitumen mastics and the high-temperature stability of bituminous mixture, however, the crack resistance of the former was related strongly with the low temperature anti-cracking performance of the latter.The three-dimensional net structure formed by basalt fiber, bitumen and aggregate could inhibit the cracking development of bituminous mixture. © 2016, Materials Review Magazine.
