| 摘 要： | 设计了纤维沥青的大尺寸试件低温拉伸断裂试验,实测了纤维沥青低温拉伸断裂时纤维的桥联应力。采用混合料低温弯曲断裂试验研究了纤维沥青混合料的低温抗裂性能,并通过对各种因素和混合料抗裂性能的灰熵关联度分析,发现了拉伸断裂试验结果与混合料低温抗裂性能有很好的相关性。 |
| 关 键 词： | 纤维沥青 拉伸断裂试验 桥联应力 混合料性能 |

| Abstract: | Low-temperature tensile fracture test was designed for large size specimen of fiber-reinforced asphalt, and the bridging stress of fiber was measured when the fracture happened.The low-temperature tensile fracture test was carried out to study the low-temperature crack resistance of firber-reinforced asphalt;through the gray entropy correlation analysis of factors and the crack resistance of asphalt mixture,it was found out that there was obvious correlation between the test results and low-temperature crac... |
| Keywords: | fiber asphalt tensile fracture test bridging stress mixture performance |
